Parker Ross TG TF TL TK Series Orbital Motor | TG0240MS030AAAB TG0195ES080AANT

Chengyuan Hydraulic offers high-performance TG, TF, TL, TK, and TJ Series orbital hydraulic motors, precision-engineered as premium replacements for Parker (Ross) industrial standards. This range covers everything from the lightweight TJ series to the ultra-heavy-duty TG/TK series, featuring core models like TG0240MS030AAAB and TG0195ES080AANT.

Serving as the primary drive force for agriculture, construction, and material handling equipment, Chengyuan ensures 100% Drop-in Interchangeability regarding mounting flanges (e.g., SAE A), drive shafts (splined or keyed), and porting. Supported by our 100% Simulation Load Testing, each motor is verified for torque output and mechanical efficiency under full pressure, ensuring smooth rotation and high reliability even at extremely low speeds.

Technical Specifications 

• Series Category: TG (Heavy Duty) / TF (Medium Duty) / TE (Standard Duty)

• Displacement Range: 140 $cm^3$/rev to 960 $cm^3$/rev (e.g., TG0240 is approx. 240cc)

• Rated Pressure: 140 bar to 200 bar (series and displacement dependent)

• Peak Pressure: Up to 280 bar (intermittent)

• Max Output Torque: Up to 1200 Nm (for TG series)

• Speed Range: 5 rpm to 600 rpm (excellent low-speed stability)

• Shaft Options: MS (1-1/4″ Keyed), ES (Splined), LW (Long Shaft), etc.

• Mounting: Standard SAE A 2-bolt/4-bolt or 4-bolt Square Wheel mount

• Housing Material: High-strength Ductile Iron

Key Technical Advantages:

• Advanced Roller Vane Technology: Utilizing a roller vane rotor set reduces startup friction and internal wear. This design ensures smooth operation at ultra-low speeds (<10 rpm) without the “jerking” effect typical of standard gerotor motors.

• High-Pressure Shaft Seal: Equipped with a patented high-pressure seal that withstands significant backpressure. This often allows for series operation without a dedicated case drain line, simplifying your hydraulic plumbing.

• Forced Lubrication Linkage: The internal drive link is lubricated via specialized flow paths, dramatically extending the motor’s life under frequent reversals or shock loads and ensuring a maintenance-free drive train.

• High Load Carrying Capacity: For TK/TG series, the bearing housing is reinforced to handle significant axial and radial loads directly from wheel drives or chain sprockets, eliminating the need for external bearings.

Application Areas:

• Agricultural Machinery: Harvester reel drives, seeder dispensing mechanisms, and sweeper brush controls.

• Construction Equipment: Auxiliary steering for wheel loaders, slew drives for mini-excavators, and truck-mounted winches.

• Material Handling: Conveyor belt drives, crane hoist motors, and forklift attachment controls.

Expert Maintenance Tips:

• Initial Priming: Before the first run, always fill the motor with hydraulic oil through the ports to prevent dry friction damage to the roller vanes during initial rotation.

• Viscosity Management: To maintain peak efficiency, use ISO VG 46 or 68 anti-wear hydraulic oil. Keep the operating temperature between 30°C and 60°C.

• Filtration Standards: Orbital motors are sensitive to particulate contamination. Maintain system return filtration finer than 20μm to protect the precision rotor set.
