Eaton Char-Lynn 2000 Series (2 Series) 2-390 High-Torque Disc Valve Motors

Product Overview: The Eaton Char-Lynn 2000 Series (commonly known as the 2 Series) represents the pinnacle of heavy-duty orbital hydraulic technology. This category highlights the highest displacement frame in the series: 2-390, featuring specific models 2-390AA2C2, 2-390AA2-E, 2-390AA2C-E, and 2-390AA4C2-E. As a premium Disc Valve motor, the 2-390 is engineered to deliver maximum output torque under continuous high-pressure and extreme load conditions. Its patented Geroler® roller set design ensures ultra-smooth operation in Low Speed High Torque (LSHT) applications. These motors are the ultimate power source for large agricultural propel drives, construction machinery wheel drives, heavy-duty industrial winches, and large-scale mixing systems.

Key Technical Advantages:

• Maximum Torque Delivery: As the largest displacement specification in the 2000 Series, the 2-390 provides superior tractive effort and driving force at comparable pressures.

• Disc Valve Precision: The independent valve plate automatically balances and compensates for wear-induced clearances, ensuring peak volumetric efficiency throughout the motor’s operational life.

• Geroler® Roller Geometry: Internal roller supports drastically reduce mechanical friction, providing smooth, pulse-free power delivery even at minimal RPM.

• Elite Load Resilience: Equipped with reinforced tapered roller bearings, the housing handles massive radial loads directly—ideal for direct-drive wheel or heavy-duty drivetrain applications.

• Technical Decoding:

  • 2-390AA2C2 / 2-390AA2C-E: Features standard 2-Bolt SAE A flanges with advanced sealing configurations for reliability in high back-pressure environments.

  • 2-390AA4C2-E: Utilizes a 4-Bolt Square flange (Wheel Mount) specifically designed for heavy-duty hub drive integration.
