Enduro Bearings MR 17287 LLU/LLB CN ABEC 5, 17x28x7

This ABEC-5 bearing features deep-groove design races with grade 10 balls, outward-facing double lip and labyrinth seals (LLU) with full contact to withstand daily use and the elements, as well as inward-facing LLB seals with lighter contact to contain 90% of the sealed synthetic high-pressure grease Mobil XHP 222. The CN air specification is the best for loose press-fit bearing bores. Radial bearings, typically used as hub bearings, can also be used as journal bearings, although the MAX type version of this bearing is better suited for use in suspension.
