Bearing ENDURO MR 22379 LLB 22x37x9 ABEC-3, C3

The Enduro MR 22379 LLB is an ABEC-3 rated radial bearing designed specifically for bottom bracket applications. It features raceways made from 52100 high-carbon chromium steel paired with Grade 10 precision balls, delivering smooth performance, reliable load handling, and long service life.

This bearing is packed with a 90% fill of high-pressure waterproof grease, providing excellent protection against moisture, dirt, and everyday wear. Its deep-groove race design allows the use of larger balls, improving durability and consistent performance under continuous load.

The most common application for this bearing is as a replacement bottom bracket bearing for Profile Racing MX BBs. Thanks to its dimensions and construction, it is well suited for applications where stability and long-term, maintenance-free operation are essential.

Dual-lip LLB seals ride in a micro-groove to form a labyrinth sealing system, offering superior protection against water and contamination while maintaining low friction. Like all Enduro bearings, it is engineered with the deepest possible race grooves to maximize bearing life.
