TG0170HW460AAAB TG0140 TG0170 TG0195 TG0240 Parker TG Torqmotor Orbital Motor

Product Overview

The TG0140, TG0170, TG0195, TG0240, TG0405, TG0475, TG0530 series and specific model TG0170HW460AAAB are Parker Torqmotor TG Series low-speed high-torque (LSHT) orbital hydraulic motors. Featuring roller-vane rotor sets, zero-leak commutation valves, and patented 60:40 spline geometry, they deliver high volumetric efficiency and superior side-load capacity. These motors are fully drop-in interchangeable with genuine Parker units and undergo 100% simulated operating condition testing, ensuring reliable performance under high pressure, high side-load, and continuous duty. Precision manufacturing and high-pressure shaft seal design make them ideal for demanding medium- to heavy-duty mobile and industrial applications.

Key Technical Advantages

• Roller-vane rotor set combined with zero-leak commutation valve delivers consistently high volumetric efficiency and exceptionally smooth low-speed performance throughout the motor’s service life.
• Patented 60:40 heavy-duty spline geometry with continuous oil-flow lubrication provides superior side-load capacity and effective cooling, extending powertrain and bearing life.
• High-pressure shaft seal withstands full system pressure, eliminating the need for a case drain line and simplifying system design.
• Full drop-in interchangeability with genuine Parker Torqmotors plus 100% simulated duty-cycle testing ensure reliable performance in high-pressure, high-flow, and heavy-duty applications while reducing OEM warranty and field maintenance costs.

Application Areas

Vehicle propulsion and drive axles, winches and hoists, auger and trencher drives, forestry and agricultural machinery (harvesters, chippers), material handling and conveyor systems, snow removal equipment, construction attachments, and a wide range of medium- to heavy-duty mobile and stationary hydraulic systems.

Expert Maintenance Tips

Verify system cleanliness and oil viscosity (mineral oil recommended; follow Parker viscosity guidelines) before installation. Ramp pressure gradually on start-up to avoid dry running. Periodically inspect shaft seals and monitor side-load conditions; keep internal spline lubrication paths clear. When replacing, use verified genuine or fully interchangeable units to ensure exact port and mounting flange match. Limit intermittent operation to no more than 10% of each minute of continuous duty. Maintain proper oil cleanliness to maximize service life.
