Empowering a Cultural Revolution in the Industrial Revolution

By Will Healy III, Industry Marketing Director, Balluff Inc.

»

LIKE IT OR not, we are leading organizations through an industrial revolution.

Digitization, Industrial IoT (IIoT), Industry 4.0, Smart Manufacturing (or whatever buzz word is your favorite) are having a major impact on our organizations. The desires of consumers for more choice, more information, and faster availability are filtering into the industrial space and the fluid power market. Manufacturers and equipment builders are actively investing in Industry 4.0 to meet these needs, but we also need to rethink our organizations and adjust our culture across all departments.

The drive for more connected machines, connected devices, and connected people is creating stress between the IT teams and the production floor (OT). Commonly called IT/OT convergence, the lack of clarity on the objectives and responsibilities of these two teams on topics like network security and data availability is creating conflict. But it doesn’t have to. Blending these teams and adding an IT/OT specialist who can communicate and relate to both departments will lead to more successful projects.

The speed at which new technology is entering the plant floor is increasing, and the value it brings to manufacturers who embrace it is impressive. Our mobile safety policies need to keep up. While use of tablets and phones is already popular, many plants are working toward the implementation of wearable technologies like AR/VR and exoskeletons. These tools provide better collaboration, maintenance, operations, training simulation, and visualization than ever before. And with 6-axis and collaborative robots, human efficiency is increased by unprecedented levels.

These technologies are pushing our organizations to a new paradigm of datadriven decision making. Mobile tools allow managers and engineers to continuously see productivity and equipment status and deep dive on problems at even the lowest levels of the automation process. Smart sensors and IIoT devices enable new insights 4

into production and empower manufacturers with data. This data drives predictive analytics programs, which increase uptime, improve asset life, and control maintenance costs like overtime and MRO. Improved technologies and increased data are drivers for success, but only with the right people in place, and unfortunately, we do not have people with the right skills and attitudes applying for our manufacturing jobs. The National Association of Manufacturer’s 2018 skills gap report states that 2.4 million U.S. manufacturing jobs will go unfilled by 2028. To remedy this, we need to embrace open talent ecosystems, utilize even more automation technologies, and develop our own talent pipeline. Generation Z is entering our workforce, and millennials need to be elevated as leaders in our organizations to be successful. Adapting to these generations requires cultural shifts, including self-directed micro-learning, social media engagement, increased diversity, new communication tools, and more crossdepartment/skillset/location collaboration.

Leaders must manage the changes that are coming at us quickly. Automation of white-collar and low-skill tasks needs to be embraced and met with re-skilling initiatives of displaced workers. Most importantly, we need a plan. In an Industry 4.0 driven change, we need the five T’s of a change plan: Team, Test, CommunicaTe, Train, & IT (OK, so maybe it isn’t entirely T’s, but let’s roll with it!). By having a team, testing the message, and communicating effectively, we can manage most changes with minimal fear and turmoil. For those workers impacted by the changes, we need to address the new skills and train them.

And please include IT in your IIoT and Industry 4.0 project teams from the beginning; you will not regret this decision.

As manufacturing joins the industrial revolution, it makes sense that the cultures of our organizations need to follow suit. More flexibility, efficiency, and visibility will drive success in both our production and culture. 

New Problem

FIGURE IT OUT

Pressure-reducing Valve Would Not Reduce the Pressure

By Robert Sheaf, CFPAI/AJPP, CFPE, CFPS, CFPECS, CFPMT, CFPMIP, CFPMMH, CFPMIH, CFPMM, CFC Industrial Training

»

A STEEL PROCESSOR had purchased a used machine and about 2 years later found the time and money to install it in their plant.

There were three manifolds with four (4) blocked center valves and a single valve subplate for a long eject cylinder.

Their maintenance group installed the power unit and piped over to the manifolds mounted on each of the four (4) stations. During start-up, the multi-valve manifolds worked well, but the single valve station had a problem. The cylinder would extend and retract, but the pressure-reducing valve would not reduce the pressure and the adjustment knob was hard to turn. They purchased a new replacement, but it did not fix the problem. They removed the counterbalance valve in the stack, but that created another problem with the cylinder drifting out when the directional valve was in the center position.

Any idea what was causing the problem?

Single Sub-Plate

If you have any questions about the details, please contact Robert Sheaf at rjsheaf@cfc-solar.com.

olution to the previous problem: Noisy pump causing foam to escape through the filler breather

S

The foaming problem oozing out of the filler breather was caused by the leaking shaft seal on the pump. When pumps are mounted on top of the reservoir, the suction line draws a vacuum with atmospheric pressure pushing the oil into the pump. However, vane and gear pumps route the case leakage back into the suction side of the pumps. Shaft seals are designed to keep oil in the pump housing and if there is a vacuum in the case, outside air can be drawn in, causing the foaming problem.

HYDRAULEX

TEAMWORK DRIVES CERTIFICATION SUCCESS

By Denise Wilson, Communications Specialist

HOW THE FORMING OF AN IN-HOUSE STUDY GROUP LED TO A SIGNIFICANT RISE IN CERTIFICATIONS.

T

en years ago, the Hydraulex plant in Detroit, Michigan had a total of three International Fluid Power Society (IFPS) certifications earned by employees across their shop floor. Today, through the actions of an in-house, employee-led Study Group movement, that number is now 22 and growing.

This remarkable rise in Hydraulex employee IFPS certifications began three years ago when a 30-year Hydraulex veteran, Steve Downey, was looking for his own path of self-improvement. He toyed with the notion of taking a few college-level classes after work so he could ultimately teach, however in the end he decided to focus on earning more IFPS certifications. Downey asked others around the plant if they were interested too, and it was from this initial search for educational opportunities that Downey came up with the idea for an in-house Study Group.

“I wanted to avoid study procrastination,” said Downey. “I believed there would be strength-in-numbers if I could convince some of my colleagues to go for their certifications as well. I started recruiting friends around the plant to see if they were interested in forming a small after-hours study group to prepare for the certification test.”

When the company got wind of Downey’s idea, they were eager to help and asked if he would open up the Study Group to the entire plant. In turn, they offered assistance in the form of providing the meeting space and study guide materials needed to prepare. Up until this time, Hydraulex had only reimbursed employees for the cost of the test after completion; the study location, training materials and travel to training and test sites, all rested on the employee’s shoulders.

When the first Study Group was formed, over 30 employees signed up. The group met once a week, after work at the plant, to work together through the IFPS study guide. After three months, they took the written test. The group didn’t do as well as they had hoped when they took the first test, however they did have some success, and more importantly, they had the 8

enthusiasm and commitment from Hydraulex to help them achieve success in the future. Now after three years of in-house Study Groups, and with the support of the company and IFPS, the pass rate on the last written test was 100% for the eight employees who took the exam.

This remarkable journey over the past three years has seen the Study Group evolve in several ways. The location for the written and hands-on portions of the tests is more assessable for employees as the company now arranges for the IFPS-supplied proctors to administer the written test on the plant site. The company also pays for the test before the employee takes it and Downey has become IFPS-certified to administer the hands-on portion of the test at the plant. This added accessibility and company support gives employees more time to focus on the test portion with less travel and up-front, out-of-pocket expenses.

IFPS took notice of the Study Group and became involved in helping them. Dan Helgerson (Technical Editor for the Fluid Power Journal), Robert Sheaf (CFC Industrial Training), Ken Dulinski (Fluid Power Instructor Macomb Community College) and Thomas Blansett (IFPS Technical Director) have supported the Study Group with answers to questions from the study guides, testing and grading support, as well as guidance for using the study manuals and access to other study materials. Making themselves accessible to the Study Groups has made a big difference in helping to keep the study momentum going.

As a result, Hydraulex is beaming with pride. According to Plant Manager Derek Weyand, “I was blown away at the amount of participation. Even though the company knocked down barriers to achieving the certifications, it still took a great deal of a person’s personal time and we are very proud of the team and honored to have played a role in their success.”

Weyand continued, “Our people are making personal accommodations to do this because they can see the success it is bringing. When the person right next to someone achieves their certifications, it shows others that they can do it too.”

Both Weyand and Downey credit three important factors to this success. First, the overall support and participation of the employees in the Study Group is a fundamental factor. They give big credit to mentorship within the ranks. While Downey initially coordinated getting the group started, he now takes on the role of mentor during the study sessions to steer the group. He concedes he doesn’t have all the answers and has learned from other participants during the sessions. Each employee has a different knowledge set, and they draw on each other to learn and take turns leading the discussion topics.

The second factor for success is company participation. Having Hydraulex commit to employees seeking certifications on the front end has made a significant difference. From paying for study materials

and the test to coordinating with IFPS for the exam to be conducted at the plant, the company has eased both the financial burden and the amount of personal time required from employees.

Lastly, Hydraulex employees understand the importance of obtaining the IFPS certifications. Employees can see first-hand that their co-workers who have acquired the certifications receive opportunity for advancement within the company. They also know that an IFPS certification is portable; it is an achievement that travels with a person regardless of what company they work for.

Of course, Derek Weyand hopes the employees stay at Hydraulex. “Our company relies heavily on the knowledge of our hydraulic technicians and specialists. Our people are building and repairing complex hydraulic equipment, and they are our number one asset. They are achieving these credentials in the same manner as they repair equipment for customers, with skill, attention to detail, and determination. As a company, we are doing our best to knock down barriers for employees to obtain their certifications.”

Weyand continued, “This is a big win for both the company and the employees. We are a growing company and it is easier for a company to grow when employees develop as ours have and can easily transition into positions that didn’t exist six months ago.” 

THIS IS A BIG WIN FOR BOTH THE COMPANY AND THE EMPLOYEES.

PNEUMATIC INDEXING DRIVES FOR

By Norman Lane, President, Rotomation

I

Position Command

ndexing drives are an essential element of many automation systems which process parts in volume. They allow sequential operations to be made on multiple parts simultaneously, thus speeding production. Most engineers are familiar with cam and servo drives for indexing, but this article introduces a simple, low-cost alternative to these traditional solutions.

Common applications in automation for repetitive rotary indexing include: • star wheels • index

tables • conveyors • escapements positioning for labeling, machining, • parts

inspection, etc.

There are at least three types of indexing drives that the engineer can choose between for these applications: cam-based drive • Mechanical

• Electrical

servo-based drive • Pneumatic

indexing drive The first two are wellknown and available from PLC many suppliers. Therefore the pneumatic index ing drive will be the focus here as an alternative to the others, which may reduce cost and complexity, in addition to adapting better to harsh environments. The following is a brief comparison of the three drives.

CAM DRIVES Cam drives have been used for many years and are capable of handling heavy loads, as well as achieving good accuracy, dynamic control, and high speed. They are typically driven by a gearmotor, with one revolution of the input for each incremental motion of the output. For synchronous machines, they are often driven by a common shaft that drives all motions in the

12

NOVEMBER 2019

machine. They are best suited for continuous indexing that does not require the motor to be started and stopped for each cycle.

CAM DRIVES

SERVO DRIVES A servo-based drive for an indexing application will include a servomotor with or without a gearbox, an encoder for position feedback, a motion controller, and an amplifier. Some of these components may be combined into integrated packages. There is normally a system controller such as a PLC overseeing the motion control, including a human interface.

PROs: `` High-speed capability `` Good accuracy and dynamic control `` Large load capacity `` Durable, rugged construction `` Energy efficient

PNEUMATIC INDEXING DRIVE

CONs: `` High cost `` Not ideal for index-on-demand `` Inflexible operation

SERVO DRIVES Positioning Controller

Servo Controller (Amplifier)

Feedback (Encoder)

PROs: `` Fully programmable speed, index, direction, acceleration, etc. `` High resolution `` Good dynamic control `` Flexible; can be repurposed easily

CONs: `` Relatively complex and expensive `` Sensitive electronics and wiring must be shielded from adverse environments `` High level of know-how to design and repair

Rotomation is one of the companies that offers a series of pneumatic indexing drives that are simple, mechanical components capable of repetitive rotary indexing with no accumulating error. They are based on rackand-pinion rotary actuators Load with the addition of one-way roller clutches and a ratchet and pawl mechanism for stopServo ping and registration of the Motor shaft. No additional control elements are needed beyond those used for any other double-acting pneumatic cylinder.

Because the motion is initiated by a standard directional control valve, they are well-suited to flexible automation where the index must occur on demand. They are robust and durable, but cannot match the controlled motion characteristics of the servo or cam drives.

PNEUMATIC INDEXER LIMITATIONS The Rotomation pneumatic indexer has operating characteristics which must be understood to obtain adequate performance. It operates in a two-step process. Typically, it is plumbed so that when in the normal (de-energized) state

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

of the control valve, the indexer is in its locked condition. In this state, the shaft will not turn in either direction, and is in a registered position defined by the internal ratchet.

Once the work has been performed and the workpiece can be moved, the control valve is shifted and the indexer resets internally. In this condition, the shaft can rotate freely in the forward direction. For this reason, horizontal shaft applications are limited to those whose weight imbalance is biased toward the reverse direction, or which have sufficient friction to avoid uncontrolled motion. A small movement will have no effect on the cycle; the load will stop at the correct location on the next drive stroke.

A related limitation of the pneumatic indexer is that it has no ability to decelerate the load directly.

This is a result of the one-way clutch used to allow the rack and pinion to reciprocate while the shaft goes in only one direction. Standard pneumatic cushions are available, which will decelerate the rack and pinion as the load approaches a stop, but the clutch will allow the inertia of the load to carry it on at its current speed. If the load has sufficient drag, either naturally or by addition of a simple drag brake, then the cushion can be effective by reducing the torque so that the drag will slow the load to a gentle stop.

PNEUMATIC INDEXING DRIVE

PROs:

ENERGY CONSUMPTION The relative amount of energy that any of these drives consume will depend on the duty cycle of the application. Cam and servo drives are both quite efficient, but differ in that the servo uses full power to hold the load in place, whereas the cam drive uses power only when moving the load. A pneumatic indexer uses compressed air, which is notoriously inefficient, but also uses no power when in the locked condition. So if the duty cycle includes a high percentage of dwell time, the advantage shifts toward the cam and pneumatic systems.

`` Low cost `` Very simple to design, implement, and maintain `` Robust construction can support the rotating load with its own bearings `` Operate in harsh environments

CONs: `` Poor dynamic control of load `` No programmability `` Air consumption (only when moving)

The Rotomation indexing actuator is a simple, robust alternative to more expensive and difficult to implement servo or cam drive systems.

Thousands of these indexers are in use around the world, providing reliable 24/7 service in a wide variety of applications. ď Ź

The Digital Revolution of Electrohydraulics

By Fabio Balzarini, Technical Sales Manager, Atos Spa.

Âť

EVERYONE CAN SEE how digital has changed our lives. Similarly, the industry sector, with the advent of the fourth revolution, where thanks to smart components, the machinery manufactured today will produce components for the market of tomorrow, will also change our lives.

Atos has always believed in the value of technology and is constantly looking for breakthrough innovations. So much so that it has become a pioneer of digitalization. Atos was the first company to offer digital electrohydraulic components on the market, with on-board diagnostics, which are completely manageable via fieldbus from the machine control unit.

At Atos, innovation is made every day with courage and determination, introducing new technologies that paved the way for further solutions that would not have been previously possible.

The first step of this long journey was to move the analog electronics on-board to the valve. We then made it digital, integrated diagnostics, and finally made it communicate with the machine control unit. Small steps have been made to make the valves more intelligent. At the same time, Atos transformed the components into a source of valuable data that was previously inaccessible with the analog electronics. The analysis of the information gathered has stimulated the development of new control strategies, which have significantly reduced valve response times, and inspired a new approach for hydraulic applications.

Later, the technology evolved with higher computing powers, larger memory, and faster

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

THEN AND NOW

communications, creating the opportunity to implement smart algorithms and features that are equipped in the valves.

For example, multiple dynamic configurations became a major asset to our customers.

This allowed them to change the valves dynamic behavior in real-time, without interruptions of the working cycle. Such technological innovations helped develop industrial ethernet, which allows real time communication with the

machine control unit; the internal oscilloscope, to monitor each phase of the cycle via USB/Bluetooth; and internal diagnostics, which saves the alarm history in the valve's permanent memory.

In parallel, the mechanics evolved in various aspects. Thanks to the CFD (Computational Fluid Dynamics) analysis, it has been possible to optimize the components performance increasing the flow rates and working pressure up to 420 bar, while the extensive stress tests conducted in our research laboratories have allowed us to increase the mechanical resistance to shock up to 50 g and reach ingress protection levels against liquids and dust to IP66/67.

In the past, we have given great emphasis to increasing performance in terms of raising efficiency and productivity. Now there is a second aspect that is becoming increasingly important: functional safety. Atos is the only electrohydraulic manufacturer in the world to produce proportional valves, certified IEC 61508 up to SIL 2 / SIL3 and ISO 13849 up to category 4, PL e.

Atos will continue to invest in innovations as long as each project is a challenge and an opportunity to define new market standards. ď Ź

NFPA Foundation Awards 11 Fluid Power Research Supplements

»

THE NFPA EDUCATION and Technology Foundation is actively working to increase the number of university students educated in fluid power, and one of the ways it does that is by supporting academic researchers in fluid power. This helps to engage current and build the careers of future university faculty who are and will be in a position to teach fluid power to undergraduate engineers on their campuses.

With this purpose in mind, the NFPA Foundation has just awarded 11 $10,000 research supplements to 11 faculty members working on fluid power research at five universities.

The recipient universities, faculty members, and research projects are: Georgia Institute of Technology • Michael Varenberg – Dynamics of rolling friction in soft-rigid interface Milwaukee School of Engineering • Paul Michael – Polymer-Enhanced Fluid Effects on Mechanical Efficiency of Hydraulic Pumps Purdue University Vacca – Individual electro-hydraulic actuators for off-road • Andrea

machines • Jose Garcia – Distributed Compact Hydraulic Regenerative Breaking for Heavy Duty Transport Vehicles University of Minnesota Chase – High Efficiency Hydraulic Pump-Motors Employing • Thomas

Partial Stroke Piston Pressurization (PSPP) • William Durfee – Hydraulic Ankle Foot Orthosis for Prescription of Orthoses for Children with CP • Perry Li – Hybrid Hydraulic-Electric Architecture for Mobile Machines • Kim Stelson – Increasing the Efficiency of Wind Turbines through Understanding of Their Transient Responses • Zongxuan Sun – Modeling and Optimization of Trajectory-Based HCCI Combustion • James Van de Ven – Efficient, Compact, and Smooth Variable Propulsion Motor University of Wisconsin – Madison • Eric Severson – Seamless Electric to Hydraulic Conversion These research projects independently represent more than $2.9 million in funding from a variety of organizations, including the U.S. Department of Energy, the National Science Foundation, and the Center for Compact and Efficient Fluid Power (CCEFP). They are an excellent sample of the growing body of fluid power research being funded by the federal government and other research organizations.

The research supplements from the NFPA Foundation are intended to provide travel support so that each faculty member and one of their graduate students can attend and present their research at a series of designated industry conferences and research summits. This will help better connect these researchers with the fluid power industry and allow better cross-fertilization of ideas. Any funds not spent on travel will be used in general support of the research project itself.

This year, the designated conferences will be the two CCEFP Summits, scheduled for October 2019 and April 2020.

WWW.IFPS.ORG • WWW.FLUIDPOWERJOURNAL.COM

Registration for the October CCEFP Summit, taking place October 22-24, 2019, is now open. NFPA members are welcome to attend this event. The CCEFP is offering two registration categories – one for NFPA members who are also CCEFP members, and one for NFPA members who are also Pascal Society donors.

FORESTRY DEMANDS FURTHER

PRODUCT DEVELOPMENT ff-highway applications are notoriously rugged and demanding.

Solutions designed for construction sites, mining, farming, and more must be up to the unique challenges of operating in dusty, unforgiving climates while handling harsh materials. But how can manufacturers and OEMs trust that their fluid power systems are built to withstand the pressure?

Enter the forestry market. Machines designed for forestry applications endure increased pressures, high flows, long duty-cycles and little downtime. However, while the conditions for forestry equipment are particularly harsh, they provide an ideal environment for designing and refining truly durable fluid power solutions.

40 YEARS OF SMALL, CONSISTENT IMPROVEMENTS Looking at the Nordic, or cut-to-length (CTL), method in forestry, there are specific conditions that contribute toward developing more reliable solutions. The CTL forestry method cuts harvested trees at the stump to specific lengths in the forest before being transported to the mill.

While this is a preferred method in regards to decreasing forest damage and improving operator safety, it does require more advanced equipment.

The machine cracks the tree with a head attached to a crane, which is then cut at one end and run through the harvester head to remove branches and leaves. Then, the tree is carefully positioned and cut at the other end to create the initial log.

These hydraulically-driven harvester heads were first introduced around 40 years ago.

But within that relatively short time frame, significant advancements have been made to orbital motors that vastly improve their lifetime efficiency and durability.

UNIQUE IN REQUIREMENTS, CONDITIONS AND FREQUENCY This harvester head, in particular, is what makes this application so unique. While it requires high speeds to move the wood through the head, it also simultaneously requires high pressures. This leads to high forces reacting on the motor due to log irregularities.

And to get the most accurate cut on the log, the positioning needs to be very exact. This may require the motors to push and pull the wood through the head to find the right measurement, creating reversing loads on the motor.

Furthermore, forestry equipment undergoes long duty-cycles.

They are typically run 24/7 through multiple operator shifts, increasing the importance of uptime and reliability. Plus, the harvesting season in forestry is much longer than a typical agriculture harvesting season. Both of these factors contribute toward longer operating hours and additional wear and tear on the equipment.

However, these harsh requirements also make it easier to gather valuable performance data. It becomes easier to predict which components wear down first and why, enabling further design improvements.

Forestry equipment operates within working conditions that aren’t usually found in other applications. While the same kind of components can be found anywhere from a small lawn mower to a large beet harvester, you won’t get the same data or feedback on how they perform as you do from those in forestry equipment.

ADVANCEMENTS AT WORK For example, we were able to design stronger shafts after learning how acceleration factored into how fast components would wear down.

We also implemented special surface treatments and other methods to increase the endurance of drivetrains and gear sets. In fact, some of these methods were developed specifically to meet the needs of forestry applications.

Over the years, we’ve also reduced pressure drop through advanced modeling capabilities. This reduces overall fuel consumption and pressure loss, greatly increasing the machine’s efficiency.

nsights gained from putting products through the ringer by way of forestry equipment has led to important innovations.

HIGH-STRESS ENVIRONMENT, HIGH REWARD With today’s technology, any manufacturer can build a respectable orbital motor. However, the trick is to ensure that it can last under harsh conditions and keep the high efficiency over the life cycle.

The differences become apparent — and more important — after 1,000 or 2,000 operating hours for hydraulic motors. And the only way to meet these demands is to subject components to the highest possible stress on the market.

Because of forestry’s role in the development of fluid power systems, the industry has been able to create the most reliable, durable and efficient systems available — regardless of market. For example, nearly every part of our orbital motor portfolio has been improved because of the forestry market.

Forestry applications in particular enable the industry to make small, but significant, adjustments year after year. It’s enabled the creation of more efficient systems that help the world do more with less, pushing boundaries and increasing the value of these systems.

After all, increased pressure turns even coal into diamonds. The same can be said for advancements in fluid power.

valve and a pilot operated check valve.

DISTINGUISH BETWEEN THE OPERATION

Pilot operated check valves provide a leak free seal, but counterbalance valves provide smoother operation when controlling the downward movement of a load. This occurs because when the pilot check valve is opened, the load may cause cylinder flow to lead delivery from the pump, and the pilot signal is lost. This causes the valve to snap closed. When delivery from the pump catches up with the cylinder, pilot pressure builds, moving the pilot piston and the valve opens. This opening and closing of the pilot piston causes a jerky motion as the pilot signal is lost and then regained. One method used to smooth out the operation is to install a flow control valve between the cylinder and the cylinder port of the check valve. Such an arrangement is shown in Fig. 30-19. This prevents flow through the check valve from leading flow from the pump and loss of the pilot signal.

YOUR CYLINDER DOESN'T GET ENOUGH RESPECT

By Brian Rooney, Professional Engineer and President, Westcoast Cylinders Inc. While multi-pump tank units and glass-enclosed control rooms get all the glory, the lowly cylinder is dutifully slaving away under a pile of debris turning fluid power into usable work. Improve your productivity by giving your cylinders some respect.

Premature cylinder wear and failure can come from many sources. From hostile operating conditions to contaminated fluid to mounting issues to rebuilds, cylinders take a silent beating. Excessive wear can also result from the original machine design or modifications to that original machine design.

However, the number one source of cylinder failure is incorrect mounting.

How does incorrect mounting show up? The main effect: side loading.

Cylinders are good at transmitting linear force, but are terrible at guiding machines. When cylinders are installed incorrectly, side load occurs as the cylinder is forced off its natural center relative to its mounting alignment. Side load can come from cylinder misalignment, cylinder binding due to mounting interference, and excessive unsupported rod extension.

HERE ARE 5 REASONS TO REMOVE SIDE LOAD ON YOUR CYLINDERS:

1

GLAND BUSHING WEAR Side loads will cause gland bushing wear between the piston rod and gland bushing bore.

The bushing is the softer material which will bear all

of the wear as the rod has a hardened surface. Cylinders that are misaligned by as little as .010” to .015” will cause this wear to occur. In order to stay aligned with the connected machine, the cylinder rod must either bend to fit or wear the gland bushing to relieve the misalignment.

2

ROD WIPER AND SEAL WEAR Side loads will cause rod wiper and seal wear.

Once the gland bushing has enough radial clearance, the seal will also begin to leak. In addition, the rod wiper will wear away enough to allow dirt and debris into the cylinder, further wearing the rod and piston seals, leading to significant fluid loss and cylinder performance degradation. The seal is now unable to keep the working fluids contained.

3

FLUID CONTROL SYSTEM CONTAMINATION Contamination that enters the cylinder will also enter the fluid control system. This happens for both hydraulic and air operations. Outside contaminants will mix with internal lubrication elements to form a pasty sludge that is difficult to purge from the cylinder and can end up in the valve system causing erratic performance and valve failure.

WWW.FLUIDPOWERJOURNAL.COM • WWW.IFPS.ORG

4

MISALIGNMENT OF INTERNAL CUSHIONS For hydraulic cylinders, worn glands can cause misalignment of the internal cushions which in turn will lead to the cushions colliding with the cushion bores in the heads. This ruins the cushion bore tolerance (which is essential for proper cushioning) and produces wear particles that will contaminate and destroy piston seals, barrels, and valve spools, and contaminate the return filters.

MISALIGNED TRUNNION-MOUNTED CYLINDERS For hydraulic cylinders, worn glands can cause misalignment of the internal cushions which in turn will lead Trunnion-mounted cylinders are more prone to the cushions colliding with the cushion bores in the heads. This ruins the cushion bore tolerance (which is essential for proper cushioning) and produces wear particles that will contaminate and to side load wear as they are only free to pivot in one destroy piston seals, barrels, and valve spools, and contaminate the return filters.

plane. The trunnion pins rigidly hold the cylinder from moving side-to-side. Mounting these cylinders require precise alignment between the rod connection to the load and the centerline of the trunnions. Most heavy assemblies tied to trunnion-mounted cylinders have a lot of sideways free motion, especially if the mechanism has been running for a few years or if there is some distance between support bearings. Any lateral movement of the connected load will introduce high-bending stresses in the rod, gland, and trunnion pins. This will cause any or all of those areas to wear excessively and/or fail catastrophically. Some large

Figure 2. Fatigue failure of a trunnion pin is often caused by excessive bending forces from cylinder misalignment.

Side load effects on a rod can also be minimized if a piston stop is incorporated into the design. The gland bushing and the piston together resist the bending stress caused by the side load.

When the cylinder is extending, the closer the piston is to the gland end head, the higher the radial forces on the piston and gland bushing. This force climbs exponentially as the piston gets near the gland end head. Imagine holding a pencil horizontally between your fingers at one end with your other hand pushing down on the other end. No amount of force on your fingers can stop the other end moving until you spread your fingers out. This is how the cylinders rod reacts.

As an example, a force of 100lbs applied at the end of a 36” stroke rod at full stroke can generate up to 900lbs of radial load on the gland bushing and piston. Adding an internal piston stop can drop this force by 50% or more.

When there are no other remedies available, the cylinder can be designed with an extended gland bushing and/or with the largest rod diameter possible in order to increase the bearing area of the gland. This reduces the wear pressure on the gland and will slow down the wear rate. The focus is to minimize the radial gland to rod pressure to reduce the rate of gland material removal.

SHOW YOUR RESPECT! Whether you remove the side load conditions or modify the cylinder to better handle the conditions, the cylinder life will be extended which will reduce machine downtime, save wasted energy, stop environmental contamination, and reduce the cost and complexity of repair to the cylinder and its mounts.

Show them some respect. They will pay you back! 

DESIGNED THE WAY YOU NEED IT! Chronic cylinder maintenance issues could be a sign that your existing design may not be optimal. HYDAC uses their years of engineering expertise, along with your feedback, to diagnose potential points of failure and find a solution that improves your performance. In this example, we designed a cylinder with a non-rotating rod and internalized piping that can be ported at a single end. This design results in less potential points of failure for less maintenance problems.

Contact us today to see how we can help you optimize your cylinder design!

Non-rotating rod feature with internalized piping and same side porting.
