Eaton Char-Lynn 2000 Series Motor | 2-290AA2-E 2-290AA4-E 2-290AA6C-E | Disc Valve Orbit Motor

Eaton Char-Lynn 2000 Series (2 Series) 2-290 Heavy-Duty Disc Valve Motors

Product Overview: The Eaton Char-Lynn 2000 Series (commonly known as the 2 Series) stands as the global benchmark for high-performance, heavy-duty orbital hydraulic technology. This category highlights the flagship high-displacement frame: 2-290, including specific models 2-290AA2C2-E, 2-290AA4-E, 2-290AA2-E, and 2-290AA6C-E. As premium Disc Valve motors, the 2-290 is engineered to deliver peak volumetric efficiency under continuous high-pressure conditions. Its patented Geroler® roller set technology minimizes startup friction and ensures ultra-smooth torque delivery at low speeds. These motors are the premier choice for harvester propel drives, construction machinery, large industrial mixers, heavy-duty winches, and injection molding equipment.

Key Technical Advantages:

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

• Elite Load Capacity: Equipped with heavy-duty tapered roller bearings, the 2 Series handles immense radial loads directly, making it ideal for direct-drive wheel or sprocket applications.

• Geroler® Roller Geometry: Precision-engineered rollers minimize internal mechanical friction, ensuring consistent power delivery in Low Speed High Torque (LSHT) conditions.

• Versatile Configurations: The AA2, AA4, and AA6 suffixes denote various mounting flanges (e.g., 2-Bolt SAE A, 4-Bolt Square) and shaft options (Keyed, Splined, or Tapered).

• Technical Decoding:

  • 2-290AA2C2-E: A standard heavy-duty configuration with specific sealing for enhanced system protection.

  • 2-290AA4-E: Optimized for specific shaft strength and torque transmission requirements.

  • 2-290AA6C-E: Tailored for seamless integration into diverse hydraulic systems.
