H414245 Wheel Bearing
The DUHUI Bearing H414245 is a single-row tapered roller bearing cone (inner ring assembly) with a 68.26 mm inner diameter and 41.28 mm cone width. This automotive wheel bearing is designed for combined radial and axial loads and is commonly used in wheel hubs, differentials, transmissions, and heavy-duty industrial applications. The matching cup for this cone is H414210, and the complete assembly is also known as H414245/H414210 or H414245/10. It serves as a direct replacement for workshops, distributors, and B2B buyers requiring a reliable bearing solution.

Product Features
- Single-row tapered roller bearing cone unit 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.
- The H414245 cone must be used with the matching cup H414210. Always replace cone and cup at the same time, preferably from the same manufacturer, to prevent fitment issues caused by different internal profiles and tolerances.
- Single-row tapered roller 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.
- Available for product customization – logo, code, pattern, or words can be applied to the bearing or packaging.
Installation Notes
- Confirm inner diameter (68.26 mm) matches your shaft before installation.
- This bearing cone must be used with the matching cup H414210.
- Single-row tapered roller bearings must be mounted in mirror-image arrangement together with a second tapered roller bearing 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. A slight preload can maximize bearing performance and service life, but excessive preload will reduce bearing life.
- Pack the bearing with high-quality grease before installation if not pre-lubricated.
