Description

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 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.
