CH 6807 2RS - Ceramic Hybrid (Radial) - 35x47x7

CH 6807 2RS - ABEC-5, Ceramic-Hybrid, Radial Bearing (C3 Clearance) - 35mm x 47mm 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 rubber seals to withstand the outside elements, and to contain the 90% fill Kluber NBU52 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. This radial bearing has been used as a hub by Bontrager and has been used as a headset bearing by Pinarello and Black Spire. 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.
