Product Description

LIC Hydraulic’s Vickers Series Vane Motors (P/N 57220857, 57477242, 57110157, 57153561) are engineered for applications requiring high speed, high efficiency, and quiet operation. These motors feature a fully balanced rotor design, which eliminates internal hydraulic side loads, ensuring long-term reliability even at peak pressures. One of the most significant advantages is the modular cartridge design, allowing for rapid field service without disconnecting the motor from the machine. We provide 100% interchangeable replacements for these Eaton Vickers part numbers, ensuring your industrial or mobile systems maintain peak productivity.

Technical Specifications (Quick Reference)

Compatible Series: 25M, 35M, 45M, 50M High Torque Vane Motors.
Rated Pressure: Up to $172\text{ bar}$ ( $2500\text{ PSI}$ ).
Max Speed: Up to $3000\text{ RPM}$ (depending on frame size).
Torque Output: High starting torque with smooth acceleration.
Rotation: Bi-directional capability for flexible installation.

Key Technical Advantages

Hydraulically Balanced: The symmetrical pressure chambers cancel out radial forces on the shaft bearings, maximizing service life and minimizing friction losses.
Low Noise & Vibration: Vane motors are inherently quieter than piston or gear motors, making them ideal for factory environments like plastic injection molding shops.
Field-Replaceable Cartridges: Downtime is minimized by the ability to swap internal cartridges. This modularity allows for quick repairs and the flexibility to change displacement sizes if system requirements evolve.
High Efficiency at High Speed: Unlike some gear motors that lose efficiency at high RPMs, the Vickers vane design maintains excellent volumetric efficiency throughout its speed range.

Application Areas

Plastic Machinery: Screw drives for injection and blow molding machines.
Winches & Hoists: Precision control for utility and industrial winch systems.
Mobile Equipment: Auxiliary drives for construction and agricultural machinery.

Expert Maintenance Tips

Proper Case Draining: Always ensure the case drain line is unobstructed and connected directly to the reservoir. Excessive backpressure in the case will blow the shaft seal and damage internal components.
Fluid Cleanliness: To protect the precision-lapped surfaces of the vanes and cam ring, maintain a filtration level of ISO 4406 18/16/14.
Startup Procedure: When installing a new 57220857 or 57477242 motor, jog the system at low pressure to ensure the vanes properly extend and seat against the cam ring before applying full load.
