The A10VSO10DRG /52R-PKC64N00 is a hydraulic variable displacement assembly manufactured by Bosch Rexroth for the A10VSO Variable Pumps series. It delivers pressurized fluid to automation circuits where flow must adjust to changing actuator demands. The geometric displacement is 10.5 cm³/rev, providing the base volume moved per shaft rotation. A fill capacity of 0.2 L indicates the oil quantity needed to prime internal passages during commissioning. The minimum inlet pressure of 0.8 bar keeps the rotating group flooded and guards against cavitation, while the maximum inlet pressure of 30 bar allows operation on boosted supply lines. A nominal pressure rating of 250 bar supports continuous duty cycles, and a maximum pressure of 315 bar tolerates brief overloads. Delivery reaches 15 L/min at 1450 rpm, matching common four-pole motor speeds, and the maximum volumetric flow of 37 L/min sets the upper boundary when speed and displacement are both at their limits.
Rotational and power metrics define how the unit couples to its prime mover and withstands dynamic loads. A maximum permissible speed of 4300 rpm marks the mechanical ceiling for short excursions, while 3600 rpm at full displacement is the highest continuous speed permitted. The moment of inertia is 0.0006 kg·m², which keeps starting torque low and enables quick acceleration in servo-controlled drives. Shaft power reaches 16 kW at 250 bar, specifying the motor size required for full-load operation, and peak torque is 42 Nm at the same pressure, indicating the twisting force transmitted through the coupling. A housing drain limit of 2 bar protects internal seals by restricting leakage oil backpressure. The pressure port carries a 1 1/16-12 UNF-2B thread to simplify high-pressure line connections, and the suction port uses the identical 1 1/16-12 UNF-2B thread so identical fittings can be stocked for both sides.
