Parker TF TG TL Series Orbital Motor | TF0100 TG0625 TL0240 | High Torque Hydraulic Motor

The TF, TG, and TL Series orbital hydraulic motors by Chengyuan Hydraulic are heavy-duty actuators fully compatible with Parker industrial standards. This range includes precision models such as TF0100EW260AAAA, TG0625EW440AAAB, and TL0240US080AAAB. Engineered with an advanced gerotor set and an integrated valve-in-star design, these motors deliver exceptional torque stability during high-load startups and low-speed operations. Our motors feature reinforced output shaft bearings designed to handle significant radial and axial loads. All units offer 100% original-place interchangeability and undergo 100% simulated condition testing, ensuring volumetric efficiency and service life that match OEM quality standards.

• Seals: Premium FKM for high-temperature and harsh fluid resistance

Key Technical Advantages:

• High-Pressure Shaft Seal: The TF/TG series is equipped with a specialized shaft seal that tolerates high backpressures without the immediate need for a case drain line, increasing system flexibility and reducing leak potential.

• Low-Noise Gerotor Geometry: Utilizing precision-ground 6-tooth or 8-tooth gear sets with self-lubricating coatings, these motors operate smoothly across the full speed range, reducing noise by $10\%$ compared to standard orbital motors.

• Heavy-Duty Tapered Roller Bearings: The TG/TL series utilizes oversized tapered roller bearings to support the output shaft, allowing the motor to directly drive heavy sprockets or gears without external bearing supports.

• Superior Low-Speed Smoothness: Thanks to precise internal volume distribution, these motors maintain constant torque output at speeds as low as $5\text{ rpm}$, eliminating “crawling” effects.

Application Areas:

• Agricultural Machinery: Combine harvester reel drives and seeder metering drives.

• Municipal Equipment: Sweeper brush drives and refuse truck winch mechanisms.

• Forestry Equipment: Feller-processor feed rollers and log conveyor systems.

Expert Maintenance Tips:

• Break-in Procedure: After initial installation, run the motor at $20\%\text{–}30\%$ of rated load for 1 hour to allow internal components to seat properly, extending service life.

• Case Drain Recommendation: While the shaft seal is robust, connecting the case drain line in high-frequency reversal or high-backpressure systems is recommended to reduce seal wear and assist in heat dissipation.

• Filtration Standard: Maintain system oil cleanliness at or above ISO 18/16/13 to prevent premature wear of the internal gerotor set.
