Overview
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.

Good questions
Get to know Enduro
There's more to Enduro than this one product. Our Enduro page has the full Enduro lineup we carry and more about the brand.
Visit the Enduro page →Why does this bearing use 52100 high-carbon chromium alloy?
52100 is the premier bearing steel alloy, known for its hardness, toughness, and resistance to wear. Using it for the deep-groove races promotes longer bearing life compared to standard steel, especially in high-load cycling applications.
What is the benefit of Grade 10 balls over standard bearing balls?
Grade 10 balls are precision-ground to very tight spherical tolerances. They roll more smoothly, produce less vibration, and maintain consistent contact with the race grooves over time compared to lower-grade balls.
Is the Mobil XHP 222 grease waterproof?
Yes. Mobil XHP 222 is a high-pressure grease formulated to resist water washout, making it well suited for bearing positions exposed to rain, trail spray, or repeated washing. It provides reliable lubrication where standard greases would degrade faster.
What riders say about the Lab
“Paul does a great job. He got my bike I bought from someone there in their town and had it packed and shipped to me in Austin, TX… It got here in perfect condition!”
“Fantastic store. It has everything you may want/need for cycling. Great team. Highly recommend to anyone looking for cycling related things and bike service.”
“I recently got back into biking and wanted to add some things onto my bike. They had most of what I was looking for in shop… I'm really happy to have found them.”
