Parker TG Series Orbital Motor | TG0960 TG0785 | TG0960EN450AAAB

The Parker TG Series from LIC Hydraulic is the definitive solution for heavy-duty orbital power. Designed to deliver superior torque and handle massive radial loads, these motors—ranging from $360\text{cc}$ to $960\text{cc}$—are the workhorses of the mobile hydraulics industry. Models like TG0960EN450AAAB and TG0960HV440AAAB are engineered for maximum reliability in punishing environments. We guarantee 100% mechanical interchangeability and subject every unit to 100% load-cycle and leakage testing, ensuring professional performance from day one.

Technical Configuration Details

• Displacement Range: TG0360, TG0405, TG0475, TG0530, TG0625, TG0785, TG0960.

• Max Torque: Up to $1490\text{ Nm}$ ($13,200\text{ lb-in}$) continuous.

• Pressure Rating: Continuous $140\text{ bar}$ ($2000\text{ psi}$); Intermittent $200\text{ bar}$.

• Mounting Options: Wheel mounts, SAE A/B flanges, and specialized 4-bolt patterns.

• Configuration Logic: The suffixes (e.g., AAAB) define high-pressure seals, specific paint finishes, and porting orientations.

Key Technical Advantages

• Massive Radial Load Capacity: Built with heavy-duty tapered roller bearings, the TG series supports significant side loads directly on the shaft, often eliminating the need for expensive external pillow blocks.

• Low-Speed Smoothness: The precision-engineered Geroler set allows for consistent rotation at ultra-low speeds, making it perfect for applications requiring high-resolution movement and steady torque.

• Robust Drive Link: The extra-large diameter drive link minimizes contact pressure and wear, providing exceptional service life even under rapid reversing and shock-load conditions.

• Superior Volumetric Efficiency: Advanced wear-compensation design ensures the motor maintains high efficiency throughout its service life, reducing fuel consumption and heat generation in the hydraulic system.

Application Areas

• Agriculture: Combine harvester reel drives, grain augers, and fertilizer spreaders.

• Construction: Compact track loader attachments, asphalt grinders, and post-hole diggers.

• Waste Management: Refuse collection trucks, shredders, and heavy-duty recycling conveyors.

Expert Maintenance Tips

• Priming Protocol: Always prime the motor with filtered hydraulic fluid before commissioning. This ensures immediate lubrication of the internal splines and Geroler surfaces upon startup.

• Back-Pressure Management: While the TG series features a high-pressure shaft seal, installing a dedicated case drain line is best practice for systems with high return-line spikes to maximize seal longevity.

• Fluid Cleanliness: To preserve the high-torque capability, maintain oil quality to ISO 4406 19/17/14 or better. Contamination is the leading cause of “slippage” or torque loss in large-displacement orbital motors.
