TG0280US080AAAB Parker TG Series LSHT Orbit Motor

Product Overview

The TG0280US080AAAB, TG0240MS030AAAA, TG0475MS051AAAB and TG0475MV460AAAA models belong to the Parker Torqmotor™ TG Series medium-duty Low Speed High Torque (LSHT) orbital hydraulic motors. Featuring a precision gerotor design, they deliver high torque, superior side-load capacity and smooth low-speed operation. Continuous oil flow across internal splines, a high-pressure shaft seal and robust roller bearings ensure long service life and consistent volumetric efficiency. Fully interchangeable with original Parker TG Series configurations (including TG0240, TG0280, TG0475), these motors are engineered for reliable drop-in replacement in agricultural, construction and material-handling systems. Every unit is validated under simulated operating conditions for dependable field performance.

Key Technical Advantages

1. Precision-machined gerotor set delivers high volumetric efficiency, smooth low-speed operation and high starting torque for frequent start-stop applications.
2. Roller bearings provide exceptional side-load capacity, ideal for direct chain, sprocket or wheel-hub drives without additional supports.
3. Continuous oil flow across internal splines minimizes wear and maintains high mechanical efficiency over extended service life.
4. Standard high-pressure shaft seal eliminates the need for case drains, simplifying plumbing and improving reliability.
5. Multiple flange, shaft and port configurations support full drop-in interchangeability with major brand equivalents.

Application Areas

Agricultural machinery (spreaders, chain conveyors), vehicle propulsion systems, winches and hoists, augers, scissor lifts, snow removal and salt/sand spreaders, material handling equipment, and light-to-medium construction machinery for drive or rotation functions.

Expert Maintenance Tips

Ensure precise flange alignment and keep side loads within rated limits during installation. Use anti-wear hydraulic oil with operating viscosity of 20–43 cSt and maintain appropriate temperature. Fully bleed the system and run at light load for initial break-in. Regularly inspect the shaft seal and fluid cleanliness (10–25 μm filtration recommended). Avoid prolonged operation above intermittent pressure ratings. In case of unusual noise or torque loss, first check system contamination and fluid condition. Use genuine Parker seal kits for service.
