CO 6902 LLB BO – Enduro Zero radial ceramic-hybrid bearing, ABEC-5, with CN clearance. Dimensions – 15mm x 28mm x 7mm.
The bearing features 52100 high-carbon chromium alloy races treated with black oxide, Grade 5 silicon-nitride ceramic balls, and dual-lip labyrinth (LLB) seals. The seals help keep out external elements and retain the 90% fill of Mobilux NGLI 2 high-pressure, waterproof synthetic grease. Si3N4 ceramic balls reduce bearing wear and increase bearing life by eliminating steel-on-steel contact inside the bearing. The black-oxide/magnetite treatment provides the races with additional corrosion resistance.
A radial bearing generally used in a hub, it can also be used as a pivot bearing, although the MAX-type version of this bearing is better suited for suspension use.
The Enduro bearing line includes bearings made of high-carbon chromium steel, 440C stainless steel, ceramic-hybrid materials, and XD15, with ceramic or stainless steel balls. The bearing races are engineered with the deepest possible grooves to accommodate the largest balls. Dual-lip seals ride in a micro-groove, creating a full labyrinth to provide better protection against the elements.
