The AA10VO140DR/31L-VSD62N00 pump is built by Bosch Rexroth for the A10VSO Variable Pumps series and supplies adjustable hydraulic flow in automated machinery. Its displacement of 140 cm³ per revolution lets engineers calculate circuit flow from shaft speed. A nominal pressure limit of 280 bar governs continuous duty, while a 350 bar peak value permits brief overloads. The shaft rotates counter-clockwise, so drive coupling must follow that direction. A SAE J744 152-4 (D) mounting flange provides a standardized interface to the prime mover. The inlet connection uses a SAE J518 2 1/2-inch port to admit fluid with low restriction. FKM seals tolerate common hydraulic oils and elevated temperatures. The housing weighs 60 kg without fluid, information needed for handling and bracket design.
System piping attaches to a SAE J518 1 1/4-inch pressure port that directs high-pressure flow to actuators. A 1 1/16-12 UN-2B case drain port returns leakage oil and keeps housing pressure low. The shaft can absorb up to 1620 Nm of input torque during acceleration, and it permits 1266 Nm of through-drive torque, although this version includes no secondary drive as indicated by the N00 code. An overhang moment limit of 4500 Nm restricts radial belt or pulley loads. Service ports are positioned on the side under the 62 N00 orientation code, which simplifies hose routing in tight installations.
