Composite air cylinders for medical and foodgrade applications

Compact Automation | compactautomation.com

The Composite Cylinder series is a linear actuator with a durable hollow rod option enabling use in vacuum pick-up applications in end-of-arm tooling. Designed in an equivalent size to Compact’s standard inch and metric series, the Composite Cylinders are 25-30% lighter than standard cylinders. This solution makes it possible for operators to either downsize a robotic application or simply handle heavier loads. The cylinder’s design also features a corrosion-resistant plastic, FDA-approved food-grade material ideal for challenging environments.

It is also suitable for medical and food grade applications or where lightweight, washdown and corrosion resistance is required. They are available in both imperial and metric sizes which makes them easily configurable and repairable. Sizes include: Inch series – ⁄2, 3 ⁄4, 1 1 ⁄8, 1 3 ⁄8, 1 5 ⁄8, and 2-in. bore, round and square body styles with strokes lengths up to 4 in. Metric series – 8, 12, 20, 25, and 40 mm bore, rectangle style body with strokes up to 100 mm. Magnetic pistons are available, as are Standard, Half-Husky and Full Husky duty types.

They are rated for operating pressures of 125 psi for ½-in., 8, and 12 mm bores and 150 psi for 3 ⁄4 – 2-in. and 20 – 40 mm bores.

Thermoplastic hydraulic hose

Kurt Hydraulics | kurthydraulics.com

Thermoplastic hose is designed for medium to highpressure applications in constricted system configurations. The product line covers SAE 100R7, SAE 100R8, and SAE 100R18 thermoplastic hose with an operating temperature from –40° to 212°F. The urethane protective covering is abrasion, ozone, and weather resistant.

SAE R100R7 nylon hose is ideal for medium pressure hydraulic systems, such as machine tool applications and lift equipment. The R7 hydraulic hose is rated between 1,000 and 3,000 psi working pressure, and 40,00 and 12,000 psi minimum burst pressure and is available in eight sizes between 1 ⁄8 and 1 in. I.D., and is also available in twin line hoses.

SAE 100R8 and SAE 100R18 thermoplastic nylon hoses are ideal for high pressure hydraulic systems, and suited for use in agricultural, plant maintenance equipment, construction equipment and similar applications. They are rated between 3,500 and 5,000 psi working pressure and 14,000 and 20,000 psi minimum burst pressure. The R8 hose is available in four sizes from 3 ⁄16 to 1 ⁄2 in. I.D., and is also available in twin line hoses.

End-of-arm sprue grippers are ideal for handling plastic materials

FIPA Inc. | fipa.com

The updated Series 90, 100, and 130 grippers now bear the red FIPA dot, which makes the gripper components immediately identifiable in installations. The series 90 grippers reliably grip small sprues due to their high closing force, wide jaw opening, and compact design while the series 100 grippers are designed to securely grip medium to large sprues, with gap-free closing for gripping thin, flat sprues.

The Series 130 grippers feature strong gripping force and a wide jaw opening, making them suitable for large sprues. FIPA grippers have a long life cycle due to their high-strength aluminum alloy housing and jaws, with a durable, corrosion-resistant anodized coating. They are rated for pressures from 2.5 to 8 bar (36.3 to 116 psi).

FIPA also offers grippers with and without “part present” monitoring. Grippers with direct monitoring feature large-area, mechanical sensor operation to detect positive gripping, regardless of the sprue dimensions or the part’s position in the gripper. Grippers with indirect part monitoring send a signal if no component has been gripped. Some models are equipped with programmable sensors with two teachable outputs. Alternatively, many sprue grippers are available with magnetic sensors. All sensors are available with either PNP or NPN switching output.

These grippers feature hydrogenated nitrile butadiene rubber (HNBR) soft pads that are wear-resistant and temperature-resistant up to 160°C (320°F) and are free of paint-wetting impairment substances (PWIS). These soft pads leave no scratches or damage even on sensitive plastic parts.

Rotary connector conveys compressed air for rotating components

Eisele Connectors Inc. | eisele-connectors.com

BasicLine ball bearing rotary connector conveys compressed air from a rigid component to a rotating component. It can rotate freely around its own axis thanks to a hybrid stainless steel ball bearing with ceramic balls, which is approved for rotational speeds of up to 800 rpm. Stainless steel versions that are suitable for other operating media will follow. The rotary connector, which is designed for an operating pressure range of -13 to 232 psi, is suitable for all applications that are compatible with nickel-plated brass. The seals are made of NBR and FKM. The rotary connector is available in a straight, an angled and a T-shaped version for tube diameters of 8, 10, and 12 mm. The screw-in end is equipped with G 1 ⁄4 threads.

Combination valve offers complete mobile motor control

Webtec | webtec.com

CV120 series combination valve provides a complete solution to hydraulic motor control for mobile machinery. It reduces space and pressure drop in machinery used for mining, quarrying, construction and agricultural applications. In addition, costs can be reduced thanks to the lower number of hoses and fittings required. It combines a variable priority flow divider with a directional control valve in one body.

Single-turn hand dial permits fast visual adjustments to the pre-determined ‘Priority’ flow. CV120 valves offer a maximum operating pressure of 250 bar (3,600 psi) and a total flow capacity of 120 lpm (32 gpm), while regulated flow capacity is 0-95 lpm (0-25 gpm). Porting choice is either 3 ⁄4 in. BSPP or 1 1 ⁄16 in. -12UN #12 SAE ORB thread sizes, although other thread sizes can be made available for special orders.

Readily biodegradable hydraulic fluids

Lubriplate Lubricants | lubriplate.com

Bio-Synxtreme HF series high-performance hydraulicfluids are designed for demanding industrial andmarine (Vessel General Permit) applications requiringenvironmental sensitivity, water solubility, fireresistance, and excellent anti-wear properties overwide temperature ranges. These Polyalkylene glycol(PAG) based fluids are available in three viscositygrades (ISO grades 32, 46 and 68) and are anhydrous(water-free).

They do not break down to form sludge, andthey do no hydrolyze in the presence of water.Furthermore, because of their high viscosity indicesand excellent low temperature characteristics, oneviscosity grade fluid may replace two or three viscositygrades.

They are available in 5 gal pails and 55 gal drums.
