A2FM series 6x Rexroth Hydraulic Axial Piston Fixed Motor

Axial piston fixed motor A2FM for explosive areas II 2G ck IIB Tx


  • Fixed motor with axial tapered piston rotary group of bent-axis design, for hydrostatic drives in open and closed circuits.
  • For use in mobile and stationary applications
  • The output speed depends on the flow of the pump and the displacement of the motor
  • The output torque increases with the pressure differential between the high-pressure side and the low-pressure side.
  • Finely graduated sizes permit far-reaching adaptation to the drive concerned
  • High power density
  • Small dimensions
  • High total efficiency
  • Good starting efficiency
  • Economical design
  • One-piece tapered piston with piston rings for sealing
  • Series 61
  • Sizes 10 to 180
  • Nominal pressure 400 bar
  • Maximum pressure 450 bar
  • Open and closed circuits

Details on explosion protection

  • Field of application according to ATEX 2014/34/EU
  • Gas: II 2G ck IIB Tx in accordance with DIN EN 13463‑1:2009, DIN EN 13463-5:2011
