Eaton Char-Lynn 4000 Series (109-) Heavy-Duty Disc Valve Orbit Motors

Product Overview: The Eaton Char-Lynn 4000 Series (109- sequence) stands as the power nucleus of heavy-duty orbital hydraulic drives. This category features the high-reliability models: 109-1158-006, 109-1294-006, and 109-1669-006. Engineered with precision Disc Valve technology and the signature Geroler® roller set, the 4000 series is built to handle high-pressure spikes and deliver sustained massive torque. Its superior bearing resilience makes it the premier choice for agricultural propel drives, large winch drives, road paving equipment, injection molding machinery, and forestry equipment.

Key Technical Advantages:

• Heavy-Duty Disc Valve Design: The independent valve plate automatically compensates for wear, maintaining peak volumetric efficiency even during high-pressure pulses for precise and stable torque delivery.

• Geroler® Roller Geometry: Incorporates roller contacts in the star-and-ring set to minimize mechanical friction, ensuring pulse-free operation in Low Speed High Torque (LSHT) conditions.

• Elite Bearing Load Resilience: Equipped with oversized tapered roller bearings, the motor shaft handles immense radial and axial loads directly—simplifying machine design by removing the need for external bearing supports.

• High-Pressure Seal Integrity: A sealing system specifically designed for high-pressure cycles ensures leak-free performance during prolonged operation in dusty, humid, or high-intensity industrial environments.

• Technical Spec Decoding:

  • 109- Series: Identifies the classic Eaton 4000 Series disc valve architecture.

  • 1158 / 1294 / 1669: Relates to displacement specifics (160cc to 625cc frames), mounting flanges, and shaft configurations.
