Parker TG Series Heavy-Duty LSHT Hydraulic Orbit Motors

Product Overview: The Parker TG Series is an elite range of disc-valve orbital hydraulic motors engineered for the most extreme and demanding operating environments. This product category features the full displacement spectrum: TG0405, TG0475, TG0530, TG0625, TG0785, and the maximum capacity TG0960.

Utilizing Parker’s patented Roller Vane technology—incorporating rollers at the tips of the stator vanes—the TG Series significantly reduces internal friction and elevates mechanical efficiency. Its defining characteristic is the oversized Tapered Roller Bearing set, allowing the motor to directly sustain massive radial and axial loads. These are the premier power units for construction propel drives, heavy-duty winches, forestry harvesters, and sweeper brush systems.

Key Technical Advantages:

• Superior Load Resilience: Integrated heavy-duty tapered roller bearings allow the shaft to handle extreme side-loading, enabling direct wheel or gear drive without auxiliary bearing supports.

• Advanced High-Pressure Sealing: Premium shaft seals manage system back-pressure spikes with ease, reducing the necessity for external case drains and providing elite protection against external contaminants.

• Roller Vane Efficiency: Compared to standard gerotors, the roller design ensures lower breakout pressure and smoother low-speed operation, extending service life by over 30%.

• Complete Displacement Range: From the mid-range TG0405 to the ultra-high displacement TG0960, offering precise power matching for any torque requirement.
