Eaton Char-Lynn 2 Series Hydraulic Motor | 2-160 2-200 2-250 | 2-160AA2U-E

LIC Hydraulic is a leading provider of the Eaton Char-Lynn 2 Series, the industry benchmark for mid-range disc valve hydraulic orbital motors. Available in popular displacements including 125, 160, 200, and 250cc, the 2 Series is engineered to deliver superior performance in demanding environments. Featuring the advanced Geroler® gear set, these motors (such as 2-160AA2U-E and 2-200AU2W4-E) offer higher efficiency, smoother low-speed operation, and longer service life compared to standard gear-type motors.

Technical Specifications (Bulleted List)

• Series: Char-Lynn 2 Series (Standard & Wheel Mount)

• Displacements: $80, 100, 125, 160, 200, 250, 315, 400, 500\text{ cc/rev}$

• Max. Pressure: Continuous up to $205\text{ bar}$ ($3000\text{ PSI}$), Intermittent up to $310\text{ bar}$.

• Torque Range: High-torque capability up to $800\text{–}900\text{ Nm}$ (size-dependent).

• Key Features: Disc valve distribution, Geroler® technology, and robust needle bearings.

Key Technical Advantages

• Optimized Disc Valve: Provides superior timing and distribution, leading to higher mechanical efficiency and less heat generation during continuous operation.

• Geroler® Gear Set: The precision rollers reduce friction between the star and ring, enabling high starting torque and consistent performance at ultra-low speeds.

• Three-Zone Pressure Design: This unique design manages internal leakage and lubrication effectively, protecting internal components during high-pressure spikes.

• High Radial Load Capacity: The heavy-duty output shaft bearings allow the motor to support significant external loads without the need for additional outboard bearings.

Application Areas

• Agricultural Equipment: Planters, sprayers, and harvesting attachments.

• Construction: Trenchers, augers, and compact track loader drives.

• Marine: Deck machinery, small winches, and net haulers.

Expert Maintenance Tips

• Case Drain Practice: To maximize shaft seal life, especially in systems with high return-line backpressure, always utilize the dedicated case drain port.

• Shaft Selection: Ensure the shaft type (e.g., Splined for high torque, Keyed for standard pulleys) matches your application’s torque transmission requirements to prevent premature shaft failure.

• Fluid Selection: Use a high-quality anti-wear hydraulic oil with a viscosity range of $20\text{–}75\text{ cSt}$ for optimal lubrication of the Geroler set.
