Product Overview
The Rexroth A6VM160HA2T/63W-VAB02000A (R902227520) is a high-performance axial piston variable displacement motor from the Bosch Rexroth A6VM series, engineered for demanding hydrostatic drive applications in both open and closed circuits. Utilizing a bent-axis rotary group design, this motor converts hydraulic pressure into rotational mechanical power with exceptional efficiency across a wide displacement range. The HA2T control variant provides automatic, load-sensing high-pressure relief and displacement control, allowing the motor to adapt its swashplate angle to system demand for optimal torque and speed regulation. With a nominal displacement of 160 cm³/rev and a robust cast-iron housing, the A6VM160 is a direct-fit replacement for OEM Rexroth installations and is widely deployed in mobile and industrial drive systems requiring precise, reliable variable-speed hydraulic power.
