TG0240HW460BBBN Parker TG Torqmotor 238cc High Torque Orbital Motor

Product Overview

The TG0240HW460BBBN and TG0195US080AAAF are precision drop-in interchangeable medium-duty high-torque low-speed orbital hydraulic motors for the Parker TG Series Torqmotor™. Featuring a heavy-duty torque link, patented 60:40 spline geometry and roller-vane design, they deliver superior side-load capacity (up to 16 000 N) and exceptionally smooth low-speed operation. Every unit undergoes 100% simulated operating-condition testing to guarantee identical mounting dimensions, performance curves and control characteristics to genuine Parker TG motors—ready for direct replacement. The range also covers TG0335, TG0280, TG0625, TG0195 and related models for reliable higher continuous pressure and torque output in medium-duty hydraulic drive systems.

Key Technical Advantages

1. Heavy-duty torque link and patented 60:40 spline geometry: Reinforced core drivetrain with continuous oil flushing of the splines enables high torque transmission and significantly extended service life.
2. High volumetric efficiency and ultra-smooth low-speed performance: Roller vanes combined with sealed commutation maintain high efficiency and shock-free output even at very low speeds, with starting torque close to theoretical values.
3. High-pressure shaft seal and case-drain-free design: Shaft seals withstand full system pressure; optimized internal flow eliminates the need for a separate case drain, simplifying plumbing and reducing leak points.
4. Superior side-load capacity and precision manufacturing: Up to 16 000 N dynamic side-load capability, high-accuracy machining of critical surfaces, premium bearings and wear-resistant materials deliver outstanding durability and low noise under continuous and intermittent high-pressure duty.

Application Areas

Agricultural machinery (augers, conveyors, harvester drives), construction equipment (skid-steer attachments, trenchers, sweeper wheel drives), forestry machines, material-handling and chain drives, winches and boom-rotate systems, vehicle propulsion, and fixed industrial hydraulic installations requiring medium-duty high-torque output.

Expert Maintenance Tips

Verify exact flange and shaft configuration match the original machine (HW = Wheel Standard with specific shaft/port options) before installation. Use clean hydraulic fluid with adequate filtration (β10 ≥ 75 recommended). Fully bleed the system prior to first operation to avoid dry running. Periodically inspect shaft and port seals; strictly observe the maximum side-load limit (16 000 N). Maintain oil temperature within recommended range and limit intermittent high-pressure operation to no more than 10% of total running time. For long-term storage, protect against corrosion and seal all ports.
