The key task of external gear motors is to convert hydraulic energy (flow and pressure) into mechanical energy (torque and rotational speed). To reduce heat loss, Rexroth external gear motors are designed to be extremely efficient. This efficiency is achieved through pressure-dependent gap sealing and high-precision manufacturing technology.

  • Consistent high quality based on large-volume production
  • Long service life
  • Slide bearings for high loads
  • Wide speed range
  • Optional reversible version for 2- and 4-quadrant operation
  • Extremely long service life (approx. 50,000 actuations)
