CH 697 LLB - Ceramic-Hybrid, ABEC-5 Radial Bearing - (C3 clearance) - 7mm x 17mm 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 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. This radial bearing is used as bearing for some derailleur pulleys. 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 possible and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
