Product Features
- Deep groove ball design accommodates radial loads and moderate axial loads in both directions – suitable for automotive and industrial applications.
- 2RS contact seals on both sides provide effective contamination protection – retains lubricant and excludes dirt and moisture.
- C3 radial internal clearance accommodates thermal expansion in higher-temperature operating conditions and high-speed applications.
- Metric configuration with 22 mm bore and 56 mm outer diameter matches OE 63/22-2RS/C3 for direct replacement.
- Heat-treated GCr15 bearing steel with precision-ground raceways – low friction coefficient and high limiting speed.
- Factory pre-lubricated – no additional greasing required before installation.
Installation Notes
- Confirm bore diameter (22.00 mm) and outer diameter (56.00 mm) match your housing and shaft before installation.
- This is a sealed bearing – do not wash or re-lubricate before installation as the factory-fill grease is pre-installed.
- C3 clearance bearings are designed for higher-temperature applications – verify suitability with your operating conditions.
- Inspect the shaft and housing for wear or damage – replace if scoring or pitting is present.
- Press the bearing squarely into the housing or onto the shaft – never apply force directly through the rolling elements.
- Torque all fasteners to vehicle manufacturer specifications.
