SKF BR25521 Wheel Bearing Race

SKF BR25521 is a tapered roller wheel bearing race built for driveline and axle service where precise fit and smooth rotation matter. With a 3.270 in outside diameter and 0.937 in width, this race is made to support consistent bearing performance in wheel-end applications.

For technicians servicing wheel bearings on vehicles such as Ford F-150 and Chevrolet Silverado applications, the BR25521 provides a direct replacement option backed by SKF’s long-standing bearing engineering experience.

Key Features

  • Wheel bearing race for tapered roller bearing assemblies
  • Outside diameter: 3.270 in
  • Width: 0.937 in
  • Logarithmic roller raceway profile for smoother rolling contact
  • Fine surface finish to support quiet operation
  • SKF manufacturing standards focused on durability and safety

Detailed Description

The SKF BR25521 wheel bearing race is engineered for wheel-end service where race geometry and surface quality affect bearing life and noise. Its tapered roller design helps maintain stable contact with the rollers, while the smooth raceway finish supports consistent operation under load. This part number, BR25521, is commonly selected for repair work that requires a precise replacement race rather than a generic universal component.

This part cross-references Timken 312518 for the same application. It is also associated with vehicle service searches for Ford F-150 and Chevrolet Silverado wheel bearing race replacement, especially when matching the correct outside diameter and width is critical.

What It Helps Address

  • Wheel bearing noise from worn race surfaces
  • Rough or uneven wheel rotation
  • Excessive bearing play caused by race wear
  • Heat and friction from degraded bearing contact surfaces
  • Service replacement needs during hub or axle bearing repair

Installation Notes and Tips

Confirm the bearing race dimensions before installation, including the 3.270 in outside diameter and 0.937 in width. Inspect the mating bearing components, hub, and spindle surfaces for wear or scoring, and replace damaged parts as needed to ensure proper bearing seating and operation.

Quality Assurance

SKF has more than 100 years of bearing engineering experience, and its products are manufactured to high quality standards for long service life and safety. BR25521 is built to meet or exceed requirements for many wheel bearing applications.
