4M-5285 External Retaining Ring
Cat® external retaining ring for vane pump bearings
Description
The vane pump bearing retaining ring is typically installed around the outside diameter of the bearing to prevent axial movement and ensure proper positioning and alignment. It holds the bearing in place and prevents it from moving or misaligning during operation, helping maintain correct bearing alignment and normal function and ensuring smooth rotation of the pump shaft.
Features
- Provides proper function and service life.
- Able to withstand high axial or radial loads, vibration and temperatures.
Applications
The vane pump bearing retaining ring is used to secure the bearing within the pump.
