Enduro Bearings MR 2437 LLU/LLB CN - ABEC 5 - 37mm x 24mm x 7mm

ABEC-5 Radial Bottom Bracket Bearing featuring 52100 High-Carbon Chromium alloy races paired with grade 5 Balls with 90% fill, high-pressure, water-proof grease.

Designed specifically for bicycle applications, the LLU/LLB seal combination on these bearings utilises a more protective full-contact, dual-lip, labyrinth (LLU) seal facing outward, towards the elements, to reduce contamination from water or dirt, while the lighter-contact (less seal-drag) LLB seal face inward to keep the grease where it belongs.

Blue side is LLU and should face outwards
Black side is LLB and should face inwards

The most common use for this bearing is as a replacement bearing for Shimano external-cup, bottom brackets with a 24mm outside diameter spindle cranksets.
