CHDRF 3041 LLB SS 30x41/44x11Bearing Ceramic Hybrid - Stainless - Double Row

This unique custom designed bearing allows you to fit 30mm cranks directly into a BB86/92 frameset. With the limitation of just 41mm inner diameter of the BB86/92 bottom bracket shell, it requires a special solution to accommodate for a 30mm BB spindle. By utilizing flanged double - row bearings that press directly into the BB shell, we are able to maximize contact area by doubling the number of balls per side to provide a long lasting solution in an extremely tight space. These Ceramic - Hybrid bearings feature 52100 High - Carbon Chromium alloy races paired with grade 5 Silicon - Nitride Ceramic Balls with 90% fill, high - pressure, water - proof grease. Sl - Ni ceramic balls rolls smoother, reduce bearing wear and increase bearing life by eliminating steel on steel contact within the bearing. This bearing is designed specifically for BB86/92 framesets and cranksets with 30mm BB spindles (BB386 and BB30). 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.
