Hydraulic motors deliver steady power even when subjected to pressure spikes, severe vibration and long duty cycles. These motors operate reliably in systems with constant starting and stopping, and sudden direction reversals.
Large radial bearings absorb piston reaction forces. Forged bronze barrels and hardened-steel pistons provide long life under adverse conditions.
Stalling, caused by barrel lift-off, is prevented by optional hold-down control. The rotating group continues to turn with full torque despite severe hydraulic shock and vibration.
System components can be smaller and lighter with these high torque motors. Compact motors, weighing 130 lb (60 kg) produce torque to 4775 lb·in at 5000 psi (540 N·m at 350 bar) with pressures to 8000 psi (560 bar).
