The AA10FM28/52W-VRC60N000 axial piston motor belongs to the A10FM Piston Motors series and is produced by Bosch Rexroth. It converts hydraulic energy into mechanical rotation for closed-circuit drives used in industrial automation. The motor has a geometric displacement of 28.5 cm³ per revolution, which defines the volume of fluid moved each cycle. At the nominal pressure of 280 bar it delivers 62.5 kW and a torque of 127 Nm, providing consistent output for medium-power tasks. When supplied with 134 l/min at the rated speed the unit operates within its designed flow range. HLP mineral oil specified under DIN 51524 is the required hydraulic fluid to ensure lubrication and wear protection. The mounting flange follows ISO 3019-1 with a two-hole pattern to fit standard pump interfaces. Alternating direction of rotation allows the shaft to run either clockwise or counter-clockwise based on circuit requirements.
The maximum working pressure is 350 bar, permitting short-term load increases above the nominal rating. A peak rotational speed of 4700 rpm extends applicability to high-speed drives while maintaining volumetric efficiency. The shaft can accept ±1000 N of axial force and up to 1200 N of radial force before bearing limits are reached. The drain port routes fluid back to tank and is limited to 4 bar, with a 3/4-16 UNF-2B thread to match common fittings. The working port uses a 3/8-16 UNC thread for secure connection of pressure lines. These mechanical, hydraulic, and connection limits outline safe operating boundaries for integration into automated hydraulic systems.
