The AA10VO60DFR/52L-VSC62K68 axial piston unit is produced by Bosch Rexroth for the A10VSO Variable Pumps series. It supplies adjustable oil flow to hydraulic actuators in automated machinery where precise displacement control is required. The pump operates with a counter-clockwise shaft rotation to match common prime movers, and its internal passages route oil from port S to port B to establish the designed flow direction. The working circuit can be loaded continuously to 4000 psi (280 bar) and can accept short-term surges up to 5100 psi (350 bar). Inlet conditions range from a minimum of 12 psi (0.8 bar) absolute to a maximum of 435 psi (30 bar) absolute, allowing the unit to work with boosted or flooded supply tanks. Fluid temperature may reach 239 °F (115 °C) without degrading service life, and all dynamic interfaces are sealed with FKM elastomers for compatibility with standard mineral oils.
The housing incorporates two case drain ports so excess leakage oil can be routed to the reservoir even when one connection is blocked by installation constraints. Drain lines must remain below 29 psi (2 bar) absolute to prevent bearing overload. The hydraulic medium may vary from 60 SUS (10 mm²/s) to 7500 SUS (1600 mm²/s), enabling cold-start operation as well as high-temperature running once viscosity drops. All pressure and suction interfaces are positioned on the side of the pump, coded 62, to simplify rigid piping inside compact power packs. These service ports follow the SAE J518 flanged pattern, while the mounting flange matches SAE J744, ensuring straightforward interchange with other frame-size pumps. Together these mechanical details let the AA10VO60DFR/52L-VSC62K68 integrate into modular hydraulic systems with minimal adapter hardware.
