ENDURO CH MR 2437 LLB ABEC-5 CERAMIC RADIAL BOTTOM BRACKET BEARING 24 X 37 X 7MM

This Ceramic-Hybrid Radial Bottom Bracket Bearing features 52100 high-carbon chromium steel races paired with Grade 5 Silicon-Nitride (Si₃N₄) ceramic balls, packed to 90% with high-pressure, waterproof grease. The ceramic balls reduce steel-on-steel contact, minimizing wear and extending bearing life.
