804358 Wheel Bearing
The DUHUI Bearing 804358 is a single-row tapered roller bearing with an 80 mm bore, 140 mm outer diameter, and 39.25 mm total width. This automotive wheel bearing is designed for combined radial and axial loads and is commonly used in rear axle wheel hub positions on commercial vehicles, trailers, and industrial applications. It matches OE specifications including 804358, 804358A, and FAG 804358, and serves as a direct replacement for workshops, distributors, and B2B buyers requiring a reliable heavy-duty bearing solution.

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, making them ideal for heavy-duty wheel hub applications.
- 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 Gcr15 chrome steel for durability and fatigue resistance. Heat-treated to 58-63 HRC for optimal wear resistance.
- Available in precision grades P0, P6, and P5 to suit different application requirements.
- Heavy-duty construction is designed for high-load applications, including commercial vehicle rear axles, semitrailers, and industrial equipment where reliability is critical.
- Available for product customization – logo, code, pattern, or words can be applied to the bearing or packaging.
Installation Notes
- Confirm bore diameter (80.00 mm) and outer diameter (140.00 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 to accommodate axial loads in both directions.
- 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.
