Product Features
- Single-row tapered roller design supports combined radial and axial loads in one direction – suitable for automotive transmission, differential, and wheel hub applications.
- Inch-series configuration with 33.338 mm bore and 73.025 mm outer diameter matches Fersa HM 88547/10 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.
- Open-type configuration supports splash lubrication and oil bath systems common in drivetrain applications.
Installation Notes
- Confirm bore diameter (33.338 mm) and outer diameter (73.025 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 vehicle manufacturer specifications – tapered rollers require proper adjustment for drivetrain and wheel hub operation.
- Lubricate with high-quality gear oil or grease – refer to the vehicle 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.
