Parker TG Series Motor | TG0475HK440AAAB | Torqmotor LSHT Hydraulic Motor

Parker Torqmotor™ TG0475 Series Heavy-Duty LSHT Hydraulic Motors

Product Overview: The Parker Torqmotor™ TG Series is the industry performance benchmark for heavy-duty orbit motors. Incorporating Parker’s patented Geroler® technology, the TG series is engineered for applications demanding extreme power density, high starting torque, and continuous operation in the harshest environments. This featured selection highlights the core configuration: TG0475HK440AAAB. With its superior heavy-duty bearing design, this motor delivers massive torque while withstanding intense radial and axial loads. It is the definitive power source for rotary drilling rigs, heavy winches, forestry attachments, and agricultural propulsion drives.

Key Technical Advantages:

• Elite Geroler® Engineering: Precision rollers at the stator-rotor contact points minimize internal friction, enhancing mechanical efficiency and ensuring pulse-free, smooth torque delivery at ultra-low speeds.

• Extreme Load Capacity: The specialized heavy-duty bearing architecture allows the motor to handle significant side loads and radial tension directly, eliminating the need for auxiliary support bearings and streamlining machine design.

• High-Efficiency Distribution: Featuring a pressure-compensated valve plate to ensure minimal internal leakage, maintaining stable power delivery even under continuous 200 Bar high-pressure conditions.

• High-Pressure Shaft Seals: Standard premium seals handle significant back pressures, providing greater flexibility in hydraulic circuit design and extending seal service life.

• Target Applications: Combine harvester propulsion, skid steer loaders, port crane winches, cold planers, and industrial shredders.
