71806 (6806) Abec 5 Bearing A/C angular contact

The Enduro 71806 cartridge bearing measures 30mm x 42mm x 7mm and meets the ABEC-5 precision standard, offering a true angular-contact design with a 15 degree contact angle. High-carbon chromium alloy races pair with grade 5 balls at 90% fill, giving the bearing a stable foundation for bottom bracket and hub applications where side loads are common.

A self-lubricating nylon cage keeps the balls separated while dual-lip seals ride in a micro-groove, forming a labyrinth that keeps out dirt and moisture; high-pressure, water-proof grease adds further protection. This bearing works as a direct replacement for BB30, PF30 and BB386 bottom brackets, and most other applications with a 30mm OD spindle, provided a small amount of preload is applied during installation.
