Co mr 17287 llb - zero ceramic (radial) - 17x28x7

CO MR 17287LB - Enduro Zero, Black-Oxide, Ceramic Hybrid, ABEC-5, radial Bearing - (C3 clearance) - 17mm x 28mm 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. A radial bearing generally used as a hub bearing, 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 andD-15 with Ceramic or stainless balls. Our bearings are always engineered with deep groove races to accommodate the largest balls possible. All of our standard bearings feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements. Static load - 488lbf / 2.17kN Weight - 13g -
