Low Speed High Torque Motor | Parker TG Series

Low Speed High Torque (LSHT) Motor | Parker TG Series

The Parker Torqmotor™ TG Series low speed high torque hydraulic motor is a rugged, high-performance solution designed for medium-duty applications such as vehicle propulsion, augers, chain drives, winches, and boom rotation systems. Built for durability and efficiency, the TG Series combines superior side load capacity, a high-pressure shaft seal, and smooth low-speed operation to deliver consistent torque and long service life.

With intermittent pressure ratings up to 4,000 psi and a maximum dynamic side load capacity of 3,600 lb at the key, this LSHT orbital motor provides exceptional power and endurance. Continuous oil flow across splines reduces wear, while Parker’s case-drain-free design simplifies installation and enhances system reliability.

Manufactured in Greeneville, Tennessee, USA, Parker’s TG Series low speed high torque motors embody the company’s commitment to quality, dependability, and proven hydraulic performance across mobile and industrial applications.
