Product Features
- Deep groove ball design accommodates radial loads and moderate axial loads in both directions – suitable for automotive and commercial vehicle applications.
- 2RS contact seals on both sides provide effective contamination protection – retains lubricant and excludes dirt and moisture.
- Metric configuration with 45 mm bore and 100 mm outer diameter matches Mercedes-Benz OE 0009818520 and SKF 6309-2RS for direct replacement.
- Heat-treated GCr15 bearing steel with precision-ground raceways – rated for 55.0 kN dynamic load and 31.5 kN static load.
- Factory pre-lubricated with grease – no additional greasing required before installation.
- Cross-referenced with FAG 6309-2RSR, NTN 6309LLU, and Timken 6309-2RS – confirmed interchange available.
Installation Notes
- Confirm bore diameter (45.00 mm) and outer diameter (100.00 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.
- 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.
