71806 LLB BB - ABEC-5, Angular-Contact, Bottom Bracket Bearing - 30 x 42 x 7mm
The ABEC-5 Angular-Contact Bottom Bracket bearing is built with 52100 High-Carbon Chromium alloy races paired with grade 5 balls and a 90% fill of high-pressure, water-proof grease. Properly installed (with the black seal for the Bottom Brackets) and adjusted, the Enduro Angular Contact (A/C) bearings distribute force across all the bearing's balls, effectively spreading it over a larger surface area. This minimizes wear and extends the bearing's lifespan, which is especially crucial in applications like Bottom Brackets, where bearings encounter constantly changing lateral loads—a primary cause for premature failures.
Primarily used as a direct replacement bearing for BB30, PF30, BB386, and most other bottom brackets featuring a 30mm OD spindle.
