Parker Torqmotor TK Series | TK0315K4640AAAA, TK0500T6640AAAB | LSHT Hydraulic Motor

Parker Torqmotor™ TK Series Heavy-Duty LSHT Orbit Hydraulic Motors

Product Overview: The Parker Torqmotor™ TK Series is a heavy-duty flagship designed for applications demanding ultimate torque and high-power density. As an industry leader in Low-Speed High-Torque (LSHT) technology, the TK series incorporates Parker’s patented Geroler® roller stator sets, ensuring reliable power delivery in the most grueling industrial and mobile environments. This featured selection includes core high-performance configurations: TK0315K4640AAAA and TK0500T6640AAAB. Equipped with extra-large heavy-duty bearings, the TK series delivers up to 1,500 Nm of torque while providing unmatched radial load capacity—making it the definitive power source for large machine propulsion, heavy winches, rotary drilling rigs, and forestry attachments.

Key Technical Advantages:

• Elite Geroler® Engineering: Precision rollers minimize internal friction, enhancing mechanical efficiency and ensuring pulse-free operation at start-up and ultra-low speeds.

• Heavy-Duty Bearing Architecture: Featuring the most robust bearing system in its class, the TK series withstands massive side loads and radial tension without the need for auxiliary supports.

• High-Pressure Shaft Seals: Standard high-pressure seals allow the motor to handle significant back pressures, simplifying system plumbing and extending service life in harsh cycles.

• Modular Versatility: * K4640 Interface: Specific splined/keyed shaft and flange combinations for seamless integration with major OEM equipment.

  • T6640 Interface: Specialized interface standards optimized for high-torque transmission in extreme-duty machinery.

• Target Applications: Harvester propulsion, rotary drill heads, skid steer loaders, port winches, and industrial shredders.
