Gear Motor FAQs

What Is a Hydraulic Gear Motor?

A hydraulic gear motor is a type of fluid power actuator that converts hydraulic energy into rotary motion. It uses intermeshing gears to deliver consistent torque and speed, making it ideal for industrial applications requiring compact and efficient power output.

What Are the Benefits of Gear Type Hydraulic Motors?

Gear type hydraulic motors are durable, cost-effective, and easy to maintain. They handle high pressures (up to 3000 PSI), support bi-rotational flow, and are well suited for demanding equipment such as conveyors, agricultural machinery, and mobile hydraulics.

What’s the Difference Between 40 Series and 1500M Series Gear Motors?

The 40 Series offers displacements from 0.50 to 1.80 cu in/rev with SAE-12 side ports, while the 1500M Series delivers 0.74 to 1.47 cu in/rev and includes 3/4" NPT rear ports. The 1500M models are also rated for pressures up to 250 PSI.

Are High-Speed Hydraulic Gear Motors Available?

Yes. Our 1500M Series gear motors can reach speeds up to 3600 RPM, making them suitable for high-speed hydraulic applications. These motors are built for reliable performance even under demanding operating conditions.
