CH 6903 LLB/29.5 ABEC-5, Ceramic, Bearing (C3 Clearance) 17mm x 29.5mm x 7mm

CH 6903 LLB/29.5 - ABEC-5, Ceramic-Hybrid, Radial Bearing (C3 Clearance) - 17mm x 29.5mm x 7mm 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. Radial bearing used as a hub bearing specifically for Industry Nine. 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.
