The AA10FM37/52W-VWC66N000 axial piston motor belongs to the A10FM Piston Motors series and is manufactured by Bosch Rexroth for hydraulic automation tasks. It provides a displacement of 36.7 cm³ per revolution so each shaft turn delivers a defined fluid volume for closed-loop drives. When operated at nominal speed, the inlet flow reaches 154 l/min to satisfy medium-flow circuits. Continuous duty is supported by a nominal pressure of 280 bar, and the unit can transmit 71.8 kW of mechanical power at this point. A maximum rotational speed of 4200 rpm permits high shaft velocity when flow is available. The direction of rotation is alternating, allowing the motor to run in either direction for reversible operation. Installation uses an ISO 3019-1 two-hole mounting flange, and the working ports are threaded 1 1/16-12 UN-2B for straightforward hose connections, while FKM seals resist common hydraulic fluids.
The case volume is 0.7 L, giving space for leakage oil and aiding internal heat dissipation. A dedicated drain port with 7/8-14 UNF-2B threads routes this oil to a low-pressure return line. Starting torque reaches 125 Nm at 280 bar, enabling smooth load acceleration from rest, and the motor can supply up to 163 Nm of torque under the same pressure during normal operation. The design withstands a maximum pressure of 350 bar so brief peaks do not damage internal components. Overall weight is 17 kg, which makes handling manageable during assembly or service. These remaining specifications define a compact piston motor suited to hydrostatic transmissions that require stable output under fluctuating load.
