BB CH 6806 LLB-bag | 30 x 42 x 7mm Bearing

CH 6806 LLB - Ceramic-Hybrid Radial Bearing - 30mm x 42mm x 7mm Ceramic-Hybrid Radial Bottom Bracket Bearing featuring 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. The most common use for this bearing is as a direct replacement bearing for BB30 and PF30 type BBs (including BB386). 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.
