Technical Data Hydraulic fluid
Selection diagram
Before starting project planning, please refer to our data sheets RE 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids) and RE 90223 (HF hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and application conditions.

Operating viscosity range For optimum efficiency and service life, select an operating viscosity (at operating temperature) within the optimum range of depending on the circuit temperature (closed circuit) and tank temperature (open circuit). Limits of viscosity range The limiting values for viscosity are as follows: Sizes 5 to 200: νmin = 5 mm2/s, short-term (t < 3 min) at max. perm. temperature of tmax = +115°C. νmax = 1600 mm2/s, short-term (t < 3 min) at cold start (p ≤ 30 bar, n ≤ 1000 rpm, tmin = -40°C) Only for starting up without load. Optimum operating viscosity must be reached within approx. 15 minutes. Sizes 250 to 1000: νmin = 10 short-term (t < 3 min) at max. perm. temperature of tmax = +90°C. mm2/s,
νmax = 1000 mm2/s, short-term (t < 3 min) at cold start (p ≤ 30 bar, n ≤ 1000 rpm, tmin = -25°C). Only for starting up without load. Optimum operating viscosity must be reached within approx. 15 minutes. Note that the maximum hydraulic fluid temperature of 115°C (90°C at size 250 to 1000) must not be exceeded locally either (e.g. in the bearing area). The temperature in the bearing area is - depending on pressure and speed - up to 12 K higher than the average case drain temperature.

Details regarding the choice of hydraulic fluid The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in a closed circuit the circuit temperature, in an open circuit the tank temperature. The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range (νopt.) - the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case. Example: At an ambient temperature of X°C an operating temperature of 60°C is set. In the optimum operating viscosity range (νopt; shaded area) this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68. Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the control temperature or tank temperature. At no point in the system may the temperature be higher than 115°C for sizes 5 to 200 or 90°C for sizes 250 to 1000. If the above conditions cannot be maintained due to extreme operating parameters, we recommend flushing the case at port U (size 250 to 1000) or using a flush and boost pressure valve (see page 28).
Filtration The finer the filtration, the higher the cleanliness level of the hydraulic fluid and the longer the service life of the axial piston unit.
Special measures are necessary in the temperature range from -40°C and -25°C (cold start phase), please contact us.
To ensure functional reliability of the axial piston unit, the hydraulic fluid must have a claenliness level of at least
For detailed information about use at low temperatures, see RE 90300-03-B.
20/18/15 according to ISO 4406.
At very high hydraulic fluid temperatures (90°C to max. 115°C, not permitted for sizes 250 to 1000) at least cleanliness level
19/17/14 according to ISO 4406 is required.
If the above classes cannot be observed, please contact us.

The service life of the shaft seal ring is affected by the speed of the motor and the case drain pressure. It is recommended that the average, continuous case drain pressure at operating temperature 3 bar absolute not be exceeded (max. permissible case drain pressure 6 bar absolute at reduced speed, see diagram). Short term (t < 0.1 s) pressure spikes of up to 10 bar absolute are permitted. The service life of the shaft seal ring decreases with an increase in the frequency of pressure spikes.

When considering the permissible axial force, the force-transfer direction must be taken into account: – Fax max = increase in service life of bearings + Fax max = reduction in service life of bearings (avoid)
Minimum inlet pressure on service line port A (B)
By selecting a suitable force-transfer direction of Fq, the stress on the bearings caused by the internal transmission forces can be reduced, thus achieving the optimum service life of the bearings. Recommended position of mating gear is dependent on direction of rotation. Examples:
To prevent damage to the motor, there must be a minimum inlet pressure in the inlet area. The minimum inlet pressure is dependent on the speed of the fixed motor.

Function
Unit dimensions
Driving/winch counterbalance valves are designed to reduce the danger of overspeeding and cavitation of axial piston motors in open controls. Cavitation occurs if the motor speed is greater than it should be for the given flow during braking, downhill travel or decrease in motor load.

Attaching the counterbalance valve
B1
When delivered, the counterbalance valve is attached to the motor using 2 tacking screws. Do not remove the tacking screws when connecting the service lines. If the counterbalance valve and motor are delivered separately, the counterbalance valve must first be attached to the motor port plate using the provided tacking screws. In both cases, the final attachment of the counterbalance valve to the motor is by the connectio of the service lines, e.g. using SAE flanges. A total of 6 screws with thread lengths B1+B2+B3 and 2 screws with thread lengths B3+B4 are required.

Installation Notes General The motor case must be completely filled up with hydraulic fluid during startup and during operation (filling the case chamber). The motor must be started up at low speed and no load until the system has been bled completely. If stopped for an extended period, fluid may drain out of the case through the service lines. When restarting, make sure that the case contains sufficient fluid. The leakage fluid inside the case chamber must be drained off to the tank through the highest case drain port. Installation position Optional. At size 10 to 200 with installation position “shaft to the top” use motor with bleeding port R (indicate in clear when ordering; the port U in the bearing section for bleeding is included in production with sizes 250 to 1000). Installation below the tank
Installation above the tank
Motor below min. fluid level in the tank (standard)
Motor above min. fluid level in tank
– Fill axial piston motor before startup via the highest case drain port
– Proceed in same way as below the tank installation
– Run the motor at low speed until the system is bled completely (bleed through service line port A, B if tubing is long) – Minimum immersion depth of leakage line in tank: 200 mm (relative to the min. fluid level in the tank). – Additional measures required for installation position 2 (shaft facing up): with installation position 2, make sure that the motor case is completely full before starting up. Bleed at port R (sizes 10 to 200) resp. U (sizes 250 to 1000). Order port R in clear text. An air pocket in the bearing area is leading to damage of the axial piston motor.
– Additional measures for installation positions 1 and 2: If stopped for an extended period, fluid may drain out of the case chamber through the service lines (air enters through the shaft seal). The bearings will therefore not be properly lubricated when the motor is started up again. Fill the axial piston motor before restarting via the highest case drain port. Installation position 2: bleed at port R (sizes 10 to 200) resp. U (sizes 250 to 1000). Order port R in clear text. – Additional measures required for installation position 2 (shaft facing up): In this installation position the bearings will not be properly lubricated, even if there is still some fluid in the case chamber. Putting a non-return valve (opening pressure 0,5 bar) in the leakage line can prevent the system emptying through the line. Installation position 1 T1

General Notes – The A2FM motor is designed to be used in open and closed circuits. – Project planning, assembly, and commissioning of the motor require the involvement of qualified personnel. – The service line ports and function ports are only designed to accommodate hydraulic lines. – During and shortly after operation, there is a risk of burns on the motor. Take suitable safety precautions, e.g. wear protective clothing – There may be shifts in the characteristic depending on the operating state of the motor (operating pressure, fluid temperature). – Tightening torques: - The tightening torques specified in this data sheet are maximum values and must not be exceeded (maximum values for screw thread). Manufacturer's instruction for the max. permissible tightening torques of the used fittings must be observed! - For DIN 13 fixing screws, we recommend checking the tightening torque individually according to VDI 2230 Edition 2003. – The data and information contained herein must be adhered to.
