Gear & Vane

For Simple Rotating Systems. Benefits Include Low Initial cost and High RPM.

Gear Motor – Simple Design, Cost Effective, and Tolerant to Dirt.

The most common type of hydraulic motor is the gear type. Gear motors, unlike the piston or vane type motors, are less susceptibility to contamination.  Simple in construction, a gear motor develops torque due to the hydraulic pressure acting on the surface of the gear teeth.

Vane Motor – Many Are Capable of Providing Rotation in Either Direction.

Vane motors typically consist of a cartridge assembly of a motor housing. This design is very similar to a vane pump. Two-port plates separate the inlet and outlet ports as they sandwich the rotor and cam ring between them.
