Eaton Char-Lynn 6K Series (6000) Heavy-Duty Disc Valve Motors

Product Overview: The Eaton Char-Lynn 6K (6000) Series is the industry-recognized standard for heavy-duty hydraulic power. This category highlights major high-displacement models: 612-4124 (6K-390) and the 6K-310cc. Utilizing Eaton’s patented Disc Valve technology and Geroler® roller set geometry, the 6K series delivers massive, consistent torque under extreme high-pressure and low-speed conditions. Its rugged cast-iron construction and high-capacity bearings make it the premier choice for construction equipment propel drives, large industrial mixers, heavy-duty winches, road cold planers, and forestry harvesters.

Key Technical Advantages:

• Advanced Disc Valve Precision: The independent valve plate automatically compensates for pressure-induced clearances, maintaining peak volumetric efficiency throughout the motor’s life, even during frequent reversals.

• Geroler® Roller Geometry: Precision-engineered roller contacts in the gear set drastically reduce startup friction, ensuring ultra-smooth performance in Low Speed High Torque (LSHT) operations.

• Elite Axial & Radial Load Capacity: Equipped with oversized tapered roller bearings, the motor shaft handles immense loads directly—ideal for direct-drive sprockets or wheel applications.

• High-Pressure Reliability: Specifically engineered for high-pressure closed or open-loop systems, offering superior resistance to pressure spikes and significant back-pressure.

• Technical Decoding:

  • 612-4124 (6K-390): 390cc frame, providing the perfect balance of power density and tractive effort.

  • 6K-310cc: A versatile choice focusing on rapid response and heavy-load reliability.
