Eaton Char-Lynn 2000 Series Motor | 2-290AA6D-E 2-290AB2-E 2-290AB6C-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) is a globally recognized benchmark for heavy-duty orbital hydraulic technology. This category highlights the flagship 290cc displacement 2-290 configurations: 2-290AA6D-E, 2-290AB2-E, 2-290AA6-E, and 2-290AB6C-E. As a high-performance Disc Valve motor, the 2-290 is engineered to deliver peak volumetric efficiency under continuous high-pressure conditions. Its patented Geroler® roller set design significantly reduces internal mechanical friction, ensuring unparalleled power stability in Low Speed High Torque (LSHT) applications. These motors are the premier choice for skid-steer attachments, construction machinery, heavy-duty conveyor drives, and agricultural propel systems.

Key Technical Advantages:

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

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

• Elite Radial Load Resilience: Equipped with reinforced tapered roller bearings, the housing handles significant radial and axial loads directly—ideal for direct-drive wheel or heavy chain-driven setups.

• Technical Decoding:

  • 2-290AA6-E / 2-290AA6D-E: Features specific flange and port configurations for seamless integration into specialized industrial machinery.

  • 2-290AB2-E / 2-290AB6C-E: Denotes high-strength output shaft types (e.g., Splined or large Keyed shafts) for high-torque transmission requirements.
