Product Features
- Single-row tapered roller design supports combined radial and axial loads in one direction – suitable for heavy-duty commercial vehicle wheel hub and axle applications.
- Inch-series configuration with 114.3 mm bore and 177.8 mm outer diameter matches Bower 64450/64700 and NTN-SNR 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 – designed to handle the high loads and torque demands of heavy-duty commercial vehicle drivetrains.
- Open-type configuration supports splash lubrication and oil bath systems common in heavy-duty axle and hub applications.
Installation Notes
- Confirm bore diameter (114.30 mm) and outer diameter (177.80 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 Volvo manufacturer specifications – tapered rollers require proper adjustment for axle and wheel hub operation.
- Lubricate with high-quality gear oil or grease – refer to the Volvo 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.
