Eaton Char-Lynn H Series Orbital Motor | 116A-164-AS-1-F | 110A 115A 116A Hydraulic Motor

LIC Hydraulic proudly presents the Eaton Char-Lynn H Series (110A/116A) Orbital Motors, the global benchmark for Low-Speed High-Torque (LSHT) performance. Engineered with the proven Gerotor technology, these motors deliver massive torque from a remarkably compact envelope. Models such as the 116A-164-AS-1-F are renowned for their smooth low-speed operation and high volumetric efficiency. Our H-series motors provide 100% original interchangeability, serving as a premium direct-fit replacement for heavy-duty agricultural, industrial, and mobile applications.

Key Technical Advantages

• Three-Zone Pressure Design: This patented internal flow management reduces mechanical drag and enhances starting torque, ensuring consistent power output even at ultra-low speeds.

• High-Capacity Bearings: Equipped with high-grade, low-friction bushings designed to handle significant radial loads, making them ideal for chain and sprocket drives.

• Heavy-Duty Drive Link: The reinforced internal drive link transfers torque with minimal wear, ensuring reliability during rapid reversals and heavy-duty cycling.

• High-Pressure Shaft Seal: Features advanced sealing geometry that accommodates high backpressures (up to 100 bar/1500 PSI), often eliminating the need for an external drain line.

Application Areas

• Agriculture: Augers, spreaders, and harvesting equipment headers.

• Conveyors: Primary drive motors for industrial processing and material handling belts.

• Turf Care: Brush drives for commercial mowers and street sweeping attachments.

• Marine: Auxiliary winch drives and net-handling systems.

Expert Maintenance Tips

• Case Drain Logic: To maximize the life of the high-pressure shaft seal, connect a case drain line if the system involves high backpressure or frequent high-speed reversals.

• Fluid Filtration: Maintain an ISO 4406 18/16/13 cleanliness level. Orbital motors are precision-fitted components; small particulates can rapidly score the Gerotor set and reduce torque output.

• Proper Priming: Before the first operation, fill the motor housing with clean hydraulic oil. Air trapped in the Gerotor can cause erratic movement and premature wear during the initial seconds of startup.
