BB 71900 LLB | 10 x 22 x 6mm Bearing

CH 3803 LLB W - Ceramic-Hybrid, ABEC-5, Extra-Wide, Double-Row, Radial Bearing (C3 Clearance) - 17mm x 26mm x 10mm This extra-wide, double-row, ABEC-5, Ceramic-hybrid bearing features 52100 High-Carbon Chromium alloy races paired with grade 5 Silicon-Nitride Ceramic Balls with 90% fill, high-pressure, water-proof grease. Si3N4 ceramic balls reduce bearing wear and increase bearing life by eliminating steel on steel contact within the bearing. This bearing size is used by Industry Nine in their rear hubs, and by Trek and Niner bike as a suspension pivot. The extra-wide double-row design greatly reduces flex in the axle of the rear hub or suspension linkage, while precisely filling the same space as two 6803 single-row bearings. 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.
