HM903249/HM903210 Wheel Bearing
The DUHUI Bearing HM903249/HM903210 is a single-row tapered roller bearing with a 44.45 mm inner diameter and 95.25 mm outer diameter. Designed for combined radial and axial loads, this automotive wheel bearing is commonly used in commercial vehicle wheel hubs, differentials, and pinion shafts. It matches OE specifications including ERF SL84/193 and Leyland 13H0997, and serves as a direct replacement for workshops, distributors, and B2B buyers requiring a reliable bearing solution.

Product Features
- Single-row tapered roller bearing design accommodates high radial and axial loads in one direction. The conical raceways allow these 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 Timken HM903249/HM903210 for straightforward replacement.
- Available for product customization – logo, code, pattern, or words can be applied to the bearing or packaging.
Installation Notes
- Confirm inner diameter (44.45 mm) and outer diameter (95.25 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.
