Installation Notes
- Confirm bore diameter (20.00 mm) and outer diameter (37.00 mm) match your hub and axle before installation .
- This bearing is sealed on both sides – seals are non-removable and protect against contamination. Do not attempt to remove or disassemble the seals .
- Inspect the hub surface and axle shaft for wear or damage before installing new components.
- Apply even pressure when pressing the bearing into the hub – never apply force directly through the rolling elements. Do not use a hammer to strike the bearing.
- Bearing is factory-lubricated and sealed – no additional greasing required before installation .
- Install in a clean environment to prevent contamination. Even small particles entering the bearing can shorten its service life.
