MR 22378 LLB A5 - ABEC-5 Radial Bearing - 22 x 37 x 8mm

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 utilizes a more protective gray LLU seal facing outward, towards the elements, to reduce contamination from water or dirt, while the lighter-contact (less seal-drag) black LLB seals facing inward keep the grease where it belongs.

The most common use for this bearings as a drive-side replacement bearing for external cup type BBs for SRAM GXP cranksets.
