CH MRF 3041/44 LLB - ABEC-5, Ceramic-Hybrid, Flanged Bottom Bracket bearing solution for BB86/92 framesets and BB30 style cranksets - 30mm x 41/44mm x 7mm

This custom designed bearing allows you to fit 30mm cranks directly into a BB86/92 frameset by utilizing flanged bearings that press directly into the BB shell to provide a clean 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 & BB30). If are looking for a more robust solution for the same BB/crankset configuration, you may also want to consider our double-row bearings in this size (DRF 3041).

The Enduro line of bearings are available in High-Carbon Chromium Steel, 440C Stainless Steel, Ceramic-Hybrid and XD-15 with Ceramic or Stainless Balls. Our bearings are always engineered with deep groove races to accommodate the largest balls possible. All of our standard bearings feature dual-lip seals that ride in a micro groove creating a full labyrinth to provide ultimate protection against the elements.
