Bearing Enduro Bearings 71806 LLB ABEC 5

71806 LLB – ABEC-5 angular-contact bottom bracket bearing, 30mm x 12mm x 7mm.

This ABEC-5 angular-contact bottom bracket bearing has 52100 high-carbon chromium alloy races and Grade 5 balls, with 90% fill and high-pressure, waterproof grease. When properly installed (with the black seal facing inward for BBs) and adjusted, Enduro angular-contact (A/C) bearings engage all the bearing's balls, spreading the force over a larger surface area to minimize wear and increase bearing life. This is particularly important in applications such as BBs, where the bearings are subject to constantly changing lateral loads, typically the primary cause of premature bottom bracket bearing failure.

This bearing is most commonly used as a direct replacement for BB30, PF30, BB386 and most other bottom brackets with a 30mm OD spindle.

Enduro bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15, with ceramic or stainless steel balls. The bearings are engineered with the deepest possible groove races to accommodate the largest possible balls. They feature dual-lip seals that ride in a micro-groove, creating a complete labyrinth to provide protection against the elements.
