BB CO 686 LLB-bx | 6 x 13 x 5mm Bearing

CO 686 LLB - Enduro Zero, Black-Oxide, Ceramic Hybrid, ABEC-5, Radial Bearing (C3 Clearance) - 6mm x 13mm x 5mm Enduro Zero, Ceramic-Hybrid, ABEC-5, radial bearing featuring black-oxide treated 52100 High-Carbon Chromium alloy races paired with Grade 5 Silicon-Nitride Ceramic Balls with dual-lip labyrinth (LLB) seals to withstand the outside elements, and to contain the 90% fill Kluber NBU52 ultra-smooth and sticky, water-proof grease. Si3N4 ceramic balls reduce bearing wear and increase bearing life by eliminating steel on steel contact within the bearing. Black oxide/magnetite treatment to the races provides an extra level of corrosion resistance and extended worry-free performance. This radial bearing has been used as a pedal bearing and as a pivot bearing on some full suspension designs though the MAX-type version of this bearing is better suited for pivot applications.. The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD15 with ceramic or stainless balls. Our bearings are always engineered with deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
