The AA10FM37/52W-VRC66N000 axial piston motor belongs to the A10FM Piston Motors series and is produced by Bosch Rexroth for hydraulic automation circuits that require compact power conversion. The unit displaces 36.7 cm³ per revolution, so each shaft turn moves a fixed oil volume through the system. At the nominal operating point it accepts 154 l/min of inlet flow and withstands 280 bar, enabling 71.8 kW of mechanical output for medium-power drives. A permitted speed of 4200 rpm supports fast cycling machines, while alternating direction of rotation lets the shaft reverse without external gearing. The ISO 3019-1 two-hole mounting flange standardizes attachment to gearboxes or housings, and a rotating group inertia of 0.0033 kg·m² keeps start-up torque demand low during frequent accelerations.
The motor tolerates 350 bar for short pressure peaks, protecting it against transient overloads. It delivers 163 Nm of torque at maximum displacement, supplying adequate force for heavy load paths. Rapid control moves are supported by a maximum angular acceleration of 4000 rad/s². The shaft can carry axial forces up to ±1500 N and radial forces of 1500 N at half the flange distance, maintaining bearing life under belt or gear tension. Working ports use a 1 1/16-12 UN-2B thread to connect directly to high-pressure lines, and case drainage is routed through a 7/8-14 UNF-2B port to relieve internal leakage. These limits and interfaces define how the AA10FM37/52W-VRC66N000 integrates into hydraulic machinery that demands reversible operation, rapid speed changes, and reliable load capacity.
