Parker Torqmotor™ TK Series Ultra Heavy-Duty Hydraulic Motors

Product Overview: The Parker Torqmotor™ TK Series is the ultimate power solution for extreme operational environments. As the highest-torque series in Parker’s orbital motor family, this page features flagship models: TK0500K664OAAAB, TK0400K5520AAAA, and TK0500K5320AAAB. The TK Series utilizes massive Geroler® roller gear sets and a reinforced drive train to deliver staggering tractive effort at low speeds. Equipped with oversized roller bearings, it can withstand immense radial loads directly. This series is widely used in large winches, heavy-duty shredders, forestry machinery, road cold planers, large-scale agricultural drives, and offshore engineering equipment.

Key Technical Advantages:

• Extreme Torque Output: Engineered to provide output torque exceeding 2500 Nm, the TK Series is the premier choice for heavy-duty industrial drives.

• Superior Radial Load Resilience: Featuring industry-leading large-scale bearing arrangements, the output shaft handles massive side loads directly, eliminating the need for external bearing supports.

• Patented High-Pressure Sealing: Parker’s patented sealing system ensures the motor remains leak-free under high back-pressure, reducing reliance on external case drain lines.

• Smooth LSHT Performance: Precision-machined roller stators ensure smooth, pulse-free power delivery even at ultra-low speeds, providing precise motion control.

• Technical Decoding:

  • TK0400 / TK0500: Represents high-displacement frames (400cc and 500cc) focused on maximum heavy-duty performance.

  • K664 / K552 / K532: Denotes specific heavy-duty mounting flanges and versatile shaft configurations (e.g., splined or large-diameter keyed shafts).
