Product Details

SKF BR28521 is engineered for manual transmission assemblies where bearing race accuracy matters. In Ford F-150, Ford F-250, Ford F-350, Bronco, and E-350 Econoline ZF transmission setups, the race helps maintain proper bearing support and smooth rotation under load. SKF has more than 100 years of engineering and manufacturing experience, and this part reflects that focus on dimensional consistency and surface quality. This part cross-references 1448T2 and 11472K for the same application.

What It Helps Address

• Rough or noisy bearing operation inside the manual transmission
• Wear at the bearing race surface
• Loss of smooth roller tracking in ZF transmission service
• Transmission rebuilds requiring a correct race dimension
• Fitment-specific replacement needs for Ford truck and van manual transmissions

Installation Notes

Verify the transmission type and bearing dimensions before installation. Confirm the outside diameter and width match the original race, and inspect the mating bearing and shaft surfaces for wear before assembly. For Ford F-150, Ford F-250, and Ford F-350 manual transmission service, match the application by year, position, and notes such as ZF transmission or pilot use where listed.

Quality Assurance

SKF manufactures this race to high quality standards for long service life and dependable operation. The brand’s long-standing engineering background supports consistent fit and finish for manual transmission repair and rebuild work.
