Guolis Enduro Bearings CO 6903 LLB Enduro Zero Juodas Oxide ABEC 5 Ceramic Hybrid

CO 6903 LLB BO - Enduro Zero, Black-Oxide, Ceramic Hybrid, ABEC-5, radial bearing (CN clearance) - 17mm 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, dual-lip labyrinth (LLB) seals with 90% fill, high-pressure, 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.

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

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.
