Parker Torqmotor™ TK Series Extreme Heavy-Duty Orbit Motors

Product Overview: The Parker Torqmotor™ TK Series is synonymous with rugged durability and extreme torque in hydraulic drive technology. This category highlights the flagship heavy-duty configurations: TK0400K5320AAAA, TK0500T4631AAA, TK0800K5640AAAB, and TK0400K5320SAAA. Utilizing advanced Disc Valve technology, the TK Series is engineered to maintain peak power efficiency under continuous high-pressure environments. Its reinforced Gerotor set ensures staggering, smooth torque delivery even at minimum speeds. These motors are the ultimate power solution for heavy-duty winches, marine deck machinery, large agricultural harvester drives, and heavy industrial mixers.

Key Technical Advantages:

• Elite Radial Load Capacity: The TK Series features industry-leading oversized bearings, capable of handling immense radial and axial forces directly—ideal for driving heavy wheel hubs without external support.

• Disc Valve Precision: The independent distribution valve automatically compensates for operational clearances, ensuring maximum volumetric efficiency throughout the motor’s service life.

• High Back-Pressure Sealing: Parker’s patented shaft seal design allows the motor to withstand high return line pressure without the need for a case drain, simplifying plumbing and enhancing reliability.

• Extreme Condition Resilience: Robust cast iron housings and high-capacity drive links ensure the motor excels in applications involving shock loads and frequent directional reversals.

• Technical Decoding:

  • TK0400 / TK0500 / TK0800: Represents displacement frame sizes of 400cc, 500cc, and 800cc respectively.

  • K5320 / T4631 / K5640: Corresponds to specific flange interfaces (e.g., SAE C) and output shaft configurations (e.g., Splined or large-diameter Keyed shafts).
