Product Features
- Single-row deep groove ball bearing design supports radial loads and moderate axial loads in both directions. Simple and robust construction requires little maintenance.
- Z – single metal shield on one side provides contamination protection while maintaining low friction for high running speeds.
- Snap ring groove on the outer ring with fitted snap ring simplifies axial location in the housing, eliminating the need for additional positioning components.
- Manufactured to OE specifications with steel rings and balls, and a sheet metal cage for durability and fatigue resistance.
- Factory-lubricated and maintenance-friendly design.
- Available for product customization – logo, code, pattern, or words can be applied to the bearing or packaging.
Installation Notes
- Confirm bore diameter (25.00 mm) and outer diameter (62.00 mm) match your housing and shaft before installation.
- The snap ring is pre-fitted on the outer ring – verify the snap ring OD matches your housing groove dimensions.
- This bearing has a single metal shield on one side. The shield is non-removable and protects against contamination.
- Inspect the housing and shaft surfaces for wear or damage before installing new components.
- Apply even pressure when pressing the bearing into the housing – never apply force directly through the rolling elements. Do not use a hammer to strike the bearing.
- Bearing is factory-preserved with oil – if pre-lubricated grease is required, pack with appropriate grease before installation. Install in a clean environment to prevent contamination.
