What Makes the Enduro MR 15267 an ABEC-5 Precision Bearing?

The Enduro MR 15267 is a high-precision radial cartridge bearing engineered specifically for bicycle applications, built with 52100 high-carbon chromium alloy race grooves designed to promote longer bearing life under sustained load. Grade 10 chromium steel balls deliver smooth, consistent rolling performance, and the dual-seal configuration pairs an LLU seal facing outward toward contamination with a lighter-contact LLB seal on the inward side to retain grease and minimize drag. Built to ABEC-5 tolerance standards, this bearing provides the dimensional accuracy and low runout that premium hubs, cranks, and suspension hardware demand.

Filled with Mobil XHP 222 high-pressure waterproof grease at a 90% fill, this bearing holds reliable lubrication under sustained load and repeated moisture exposure. The 15mm x 26mm x 7mm form factor covers a bicycle-specific dimension found in cranksets, hubs, and suspension linkages where standard 6xxx series bearings won't fit. For mechanics who need a precise dimensional match with genuinely high-quality construction behind it, the MR 15267 is the bearing to spec.
