Product Features
- Single-row tapered roller design supports combined radial and axial loads in one direction – suitable for Isuzu commercial vehicle wheel hub, axle, and transmission applications.
- Metric-series configuration with 35 mm bore and 80 mm outer diameter matches Isuzu OE SC070821 for direct replacement.
- Separable cup and cone construction simplifies installation and maintenance – inner ring with roller assembly can be mounted independently.
- Heat-treated GCr15 bearing steel with precision-ground raceways ensures consistent load distribution and wear resistance in demanding commercial vehicle applications.
- Open-type configuration supports splash lubrication and oil bath systems common in heavy-duty axle and hub applications.
Installation Notes
- Confirm bore diameter (35.00 mm) and outer diameter (80.00 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 Isuzu manufacturer specifications – tapered rollers require proper adjustment for axle and wheel hub operation.
- Lubricate with high-quality gear oil or grease – refer to the Isuzu 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.
