Eaton Char-Lynn 2000 Series (2 Series) 2-250 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 drive technology. This category highlights the flagship 250cc 2-250 configurations: 2-250AA2A-E, 2-250AA2B-E, 2-250AA2C-E, and 2-250AA2D-E. As a premium Disc Valve motor, the 2-250 is engineered for peak volumetric efficiency under continuous high-pressure and extreme load 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 propel drives, heavy industrial mixers, construction machinery, forestry equipment, and injection molding drives.

Key Technical Advantages:

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

• Geroler® Roller Geometry: Precision-engineered roller contacts in the gear set drastically reduce mechanical friction, ensuring smooth, pulse-free operation at minimal speeds.

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

• Technical Decoding:

  • 2-250AA2A-E / 2-250AA2B-E: Denotes specific shaft ends and porting configurations for precise mechanical matching.

  • 2-250AA2C-E / 2-250AA2D-E: Focuses on system integration compatibility with various sealing and mounting options.
