Product Features
- Single-row tapered roller bearing design accommodates high radial and axial loads in one direction. The conical raceways allow these versatile bearings to support combined loads effectively.
- Separable cone and cup components simplify mounting, dismounting, and maintenance. The cone unit consists of an inner ring with cage and roller set, while the cup is the outer ring.
- Manufactured to OE specifications with case carburized steel for durability and fatigue resistance.
- Pressed steel cage provides reliable roller guidance under load.
- Direct interchange with multiple major brand equivalents including NSK HM88547/HM88510, KOYO HM88547/10, and Fersa HM 88547/10.
- Available for product customization – logo, code, pattern, or words can be applied to the bearing or packaging.
Installation Notes
- Confirm inner diameter (33.34 mm) and outer diameter (73.03 mm) match your housing and shaft before installation.
- This is a single-row tapered roller bearing – these bearings must be mounted in mirror-image arrangement together with a second tapered roller bearing. Paired bearing sets can be applied in X, O, or tandem arrangements.
- Inspect the housing and shaft surfaces for wear or damage before installing new components.
- Apply even pressure when pressing the cone onto the shaft and the cup into the housing – never apply force directly through the rolling elements.
- Proper bearing preload is critical for tapered roller bearings – refer to the vehicle service manual for torque specifications.
- Pack the bearing with high-quality grease before installation if not pre-lubricated.
