Product Features
- Single row tapered roller design accommodates combined radial and axial loads in wheel hub and driveline positions.
- Inch-series dimensions of 50.80 mm bore and 85.00 mm outer diameter match standard 18790/18720 envelope for direct interchange.
- Cone and cup are separable for simplified mounting and maintenance access.
- Case carburized steel construction provides wear resistance under repeated load cycles.
- Cross-references to SKF, Timken, NTN, and NSK part numbers support easy sourcing verification.
Installation Notes
- Verify the 50.80 mm bore diameter and 85.00 mm outer diameter match your wheel hub or axle application before installation.
- Inspect the axle spindle and hub bore for wear or damage. Clean all mating surfaces before pressing the bearing.
- This bearing set includes the cone (18790) and cup (18720). Confirm both components are correct for your application.
- Set bearing endplay or preload according to the vehicle manufacturer’s specification. Tapered roller bearings require proper adjustment for optimal service life.
- Use a proper bearing press and adapter set. Do not strike the bearing directly during installation.
