Product Features
- Single-row tapered roller design supports combined radial and axial loads in one direction – suitable for automotive wheel hub, transmission, and axle applications.
- Inch-series configuration with 57.15 mm bore and 96.838 mm outer diameter matches Timken SET 76 and Fersa 387 AS/382 A equivalents 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.
- Cross-referenced with Timken SET 76 – confirmed interchange available.
Installation Notes
- Confirm bore diameter (57.15 mm) and outer diameter (96.838 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.
