CO MR 18307LB - Enduro Zero, Black-Oxide, Ceramic Hybrid, ABEC-5, radial Bearing (C3 clearance) - 18mm x 30mm x 7mm -
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 Mobilux NGLI 2 high pressure water proof synthetic 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.
Radial bearing generally used as a hub bearing, as bottom bracket bearing for some older square taper BBs, and can be used as a pivot bearing though the MAX-type version of this bearing is better suited for suspension use. Quite often This bearing replaces bearings marked 6903 in front hubs from DT Swiss, Giant and Bontrager, though the ID of This bearing is 1mm larger than a standard 6903.
The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15 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.
