Eaton Char-Lynn 2000 Series (2 Series) 2-125 Heavy-Duty Disc Valve Motors

Product Overview: The Eaton Char-Lynn 2000 Series (commonly known as the 2 Series) is the global standard for heavy-duty orbital hydraulic technology. This page features the flagship 2-125 configurations: 2-125AA2C2-E, 2-125AA42-E, 2-125AA2-E, and 2-125AA4C-E. As a premium Disc Valve motor, the 2-125 is engineered to deliver superior volumetric efficiency under rigorous conditions. Its patented Geroler® roller set design ensures consistent, powerful torque delivery even at low speeds. These motors are the premier power source for agricultural machinery (harvesters), construction equipment (skid-steer attachments), heavy-duty winches, injection molding machines, and industrial drive systems.

Key Technical Advantages:

• Disc Valve Precision: The independent valve plate automatically compensates for wear-induced clearances, providing higher volumetric efficiency and more precise power delivery than standard spool valve motors.

• Geroler® Roller Geometry: Precision-engineered roller contacts in the gear set drastically reduce internal mechanical friction, ensuring smooth, pulse-free operation in Low Speed High Torque (LSHT) conditions.

• Elite Load Resilience: The 2 Series features a reinforced tapered roller bearing system capable of handling significant radial and axial loads, ideal for chain-driven or direct-drive wheel applications.

• Technical Decoding:

  • 2-125AA2C2-E: A heavy-duty configuration with specialized sealing for enhanced system protection.

  • 2-125AA42-E / 2-125AA4C-E: Denotes specific mounting flanges (e.g., 4-Bolt Square) and diverse shaft configurations.
