Motors & Systems

ROL-SEAL HYDRAULIC MOTORS

Unique rolling abutment design offers smooth low speed, high torque with a proven measurable difference. Compare with all others – gerotor, piston, and gear.

Benefits:

  • Higher starting torque.
  • Increased vehicle gradeability.
  • Less torque “ripple”.
  • Less torque “droop” at high speed.
  • More useable speed over entire range.
  • Double-ended shaft capability.

AXIAL VANE HYDRAULIC MOTORS

The ultimate hydraulic design for smooth, precise, repeatable positioning applications such as robotics.

Benefits:

  • Accurate, repeatable positioning.
  • Case drain leakage is so low that a servo valve can easily control speed and position.
  • Mechanically and hydraulically “stiff.”
  • Smooth slow-speed operation.
  • High starting torque.
  • Fewer wearing parts, exceptional life.

OVERHUNG LOAD ADAPTERS

Complete line of overhung load adapters to meet the demands of agricultural, mobile and industrial applications.

Benefits:

  • Keyed / splined shafts
  • Higher side / thrust loads.
  • Increase motor or pump life.
  • Standard duty / heavy duty bearings
  • Special or SAE “A”, “B”, “C”, “C-C” mounts

HYDRAULIC MOTOR BRAKES

Von Ruden rear-mounted, normally on, wet friction disc-type brakes for Rol-Seal and Axial Vane motors. Prevent creep under high static load, or where positive locking of motor shaft is required. Choice of torque capacity.
