Eaton Char-Lynn 2000 Series Motor | 2-130 2-200 2-250 2-390 AA2U-E | Disc Valve Orbit Motor

Eaton Char-Lynn 2000 Series (2 Series) AA2U-E Heavy-Duty Disc Valve Motors

Product Overview: The Eaton Char-Lynn 2000 Series (commonly known as the 2 Series) is a world-renowned benchmark for heavy-duty orbital hydraulic technology. This category focuses on the premium AA2U-E configuration matrix, including models: 2-130AA2U-E, 2-200AA2U-E, 2-250AA2U-E, 2-290AA2U-E, 2-315AA2U-E, and 2-390AA2U-E. As a high-end Disc Valve motor, the AA2U-E series is engineered for peak volumetric efficiency under continuous high-pressure conditions. Its patented Geroler® roller set technology ensures agile response during start-stops and delivers unparalleled power stability in Low Speed High Torque (LSHT) applications. These motors are the premier choice for harvester drives, skid-steer attachments, heavy industrial mixers, forestry equipment, and injection molding machinery.

Key Technical Advantages:

• AA2U-E Specification: Features standard 2-Bolt SAE A mounting flanges and high-spec porting, ensuring seamless integration into a wide range of industrial and mobile equipment.

• Disc Valve Precision: The independent valve plate automatically balances and compensates for wear-induced clearances, providing superior efficiency compared to spool valve motors.

• Geroler® Roller Geometry: Precision-engineered rollers minimize internal mechanical friction, ensuring smooth, pulse-free operation at minimal speeds.

• Elite Load Resilience: Equipped with reinforced tapered roller bearings, the 2 Series handles immense radial loads directly, ideal for direct-drive wheel or heavy chain-driven applications.
