Product Features
- Single-row tapered roller design supports combined radial and axial loads in one direction – suitable for heavy-duty commercial vehicle transmission, differential, and wheel hub applications.
- Metric-series configuration with 55 mm bore and 120 mm outer diameter matches SKF 31311J2, Timken 31311, and FAG 31311A equivalents for direct replacement.
- Separable cup and cone construction simplifies installation and maintenance – inner ring with roller assembly can be mounted independently.
- Heat-treated bearing steel with precision-ground raceways – rated for 152 kN dynamic load and 173 kN static load for demanding commercial vehicle drivetrains.
- Open-type configuration supports splash lubrication and oil bath systems common in heavy-duty axle and hub applications.
- Cross-referenced with DAF OE 0510440 and multiple major brands – confirmed interchange available.
Installation Notes
- Confirm bore diameter (55.00 mm) and outer diameter (120.00 mm) match your existing bearing and housing before installation.
- Inspect the shaft and housing for wear or damage – replace if scoring or pitting is present.
- Set bearing preload according to DAF manufacturer specifications – tapered rollers require proper adjustment for axle and wheel hub operation.
- Lubricate with high-quality gear oil or grease – refer to the DAF service manual for viscosity grade and lubrication method.
- When paired with a second tapered roller bearing, mount in mirror-image arrangement to accommodate axial loads in both directions.
