Bosch Rexroth A4FM Axial Piston Motor


The Bosch Rexroth A4FM motor is a high pressure, fixed displacement axial piston motor. It is for use in open and closed loop circuits for hydrostatic drives and is well suited for applications, where compact installation size is required.

Output speed is proportional to input flow and inversely proportional to motor displacement. The Output torque increases with the pressure drop across the motor between the high and low-pressure sides.

The A4FM motor is available in displacement sizes: 22 | 28 | 40 | 56 | 71 | 125 | 250 | 500 cc/rev. Nominal pressure is 350 bar, maximum pressure is 400 bar.

Other features of the Bosch Rexroth A4FM motor include:

  • High tolerance to torsional vibrations;
  • Long service life at high pressures;
  • Very high total efficiency;
  • Low operating noise;
  • Swashplate design;
  • Optimum efficiencies.
