CH MR 19285LB - ABEC-5, Ceramic-Hybrid, radial bearing C3 clearance) - 19mm x 28mm x 5mm - This ABEC-5, Ceramic-hybrid bearing features deep-groove design 52100 High-Carbon chromium alloy races, with grade 5 Silicon-Nitride Ceramic balls, 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. A bit of an oddball size, this bearing generally used as a hub bearing, specifically for Fulcrum rear wheels. 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.
