61806/29 LLU/LLB - ABEC-5 Radial Bearing (C3 Clearance) - 29 x 42 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 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 bearing is as a direct replacement bearing for BB30 and PF30 type BBs with SRAM DUB cranksets.
