CO 6805 LLB - ABEC-5, Enduro Zero, Ceramic-Hybrid Black Oxide treated radial bearing - 25mm x 37mm x 7mm -

Enduro Zero Ceramic-Hybrid Radial bottom bracket Bearing featuring Black-Oxide treated 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. Black oxide/magnetite treatment to the races provides an extra level of corrosion resistance and extended worry-free performance. Dual-lip, light-contact labrynth seals (LLB) provide superior protection from the elements and keep the Kluber Isoflex NB52 grease where it belongs.

The most common use for this bearing is as a direct replacement bearing for Shimano external cup BBs when using the plastic Shimano bearing insert. If you wish to avoid using the plastic insert, MR 2437 is the correct bearing for the job

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 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.
