Parker TG Series Motor | TG0785MS861AAAA, TG0625MS050AAAB | Torqmotor LSHT

Parker Torqmotor™ TG Series Large Displacement LSHT Hydraulic Motors

Product Overview: The Parker Torqmotor™ TG Series sets the durability standard in the LSHT (Low-Speed High-Torque) hydraulic motor industry. Utilizing Parker’s patented Geroler® roller stator technology, this series is specifically engineered for heavy-duty applications that demand high radial load capacity and extreme shock torque resilience. This selection highlights the powerhouse models: TG0785MS861AAAA (one of the largest in the series) and TG0625MS050AAAB. These motors are the preferred drive choice for heavy travel drives, forestry attachments, industrial shredders, and high-load winch systems, delivering unmatched smooth power at low speeds.

Key Technical Advantages:

• Superior Geroler® Technology: Compared to standard Gerotor designs, the rollers minimize friction, providing higher mechanical efficiency at start-up and consistent performance throughout the motor’s lifespan.

• Heavy-Duty Bearing System: The TG series features the most robust bearing arrangement in its class, allowing the motor to handle massive radial forces directly, ideal for direct-drive wheel or sprocket applications.

• High-Pressure Shaft Seals: Standard high-performance seals withstand back pressures up to 200 Bar, offering greater flexibility in hydraulic circuit design and reducing internal leakage risks.

• Rugged All-Metal Internals: High-strength alloy steel shafts and rotors ensure an extended service life under frequent reversals and extreme load fluctuations.

• Target Applications: Combine harvester propulsion, skid steer loader power heads, large industrial mixers, and municipal cold planers.
