Product Description
LIC Hydraulic offers the Eaton Char-Lynn 105 Series, a heavy-duty orbital hydraulic motor engineered for the most demanding environments. Our featured model, 105-1139-006 (also known as 105-1139), represents the pinnacle of LSHT (Low Speed High Torque) technology. Utilizing the patented Geroler® motor element and advanced Disk Valve distribution, the 105 series provides superior volumetric efficiency and consistent performance across a wide range of speeds. Whether you are operating 101, 103, or 104 series motors, the Char-Lynn design ensures high-pressure capability and industry-leading durability for both mobile and industrial machinery.
Technical Specifications (Bulleted List)
Series: Char-Lynn 105 Series (Compatible with 4000 Series)
Model: 105-1139-006 / 1051139006
Motor Type: Orbital / Geroler® Piston Style
Distribution: Disk Valve (Self-compensating for wear)
Max Pressure: Continuous up to $250\text{ bar}$ ($3600\text{ PSI}$)
Mounting: Standard 4-Bolt or Magneto configurations available.
Key Technical Advantages
High Start-up Torque: The Geroler® design incorporates precision-engineered rollers that reduce friction during startup, allowing the 105-1139 to move heavy loads with minimal pressure input.
Integrated Heavy-Duty Bearings: Designed to handle significant radial and axial loads, making it ideal for direct-drive applications like vehicle wheels or heavy conveyor pulleys.
Advanced High-Pressure Shaft Seal: Features an industry-leading seal design that tolerates high backpressures, often eliminating the need for a separate case drain line in many circuit designs.
Optimized Disk Valve Timing: The self-rectifying disk valve minimizes internal leakage and ensures the motor maintains precise speed control even under varying load conditions.
Application Areas
Agriculture: Header drives for combines, grain augers, and sprayers.
Construction: Skid steer loader attachments, trenchers, and vibratory rollers.
Marine & Industrial: Winch drives, heavy-duty mixers, and waste processing equipment.
Expert Maintenance Tips
Initial Priming: Always fill the motor with clean hydraulic fluid before startup. Dry rotation can score the precision surfaces of the Geroler® element.
Filtration Standard: To protect the high-precision disk valve, maintain a filtration level of at least $ISO\text{ 18/16/13}$. Contamination is the leading cause of “spool-up” failure in orbital motors.
Check Case Pressure: While the 105-1139 has a robust seal, if your system involves frequent reversals or high-speed overrunning, installing a case drain line will significantly extend the life of the shaft seal.
