Enduro Bearings - World leader in cycling-specific bearings! - A3 Series

Your wheels spin more than any other part of your bike, and having the best bearings for this application is crucial to producing the best performance. At Enduro bearings, we design our hub bearings for maximum performance and longevity for this specific application. Our hub bearings feature deep grooves in the races to accommodate the most enormous balls possible, to help withstand the constantly changing multidirectional loads we put on them. We also utilize premium materials to ensure longevity. We design and source all of the various bearing components (balls, races, seals, and grease) from suppliers worldwide.The Enduro line of hub bearings is available in high-carbon chromium steel, black-oxide-treated chromium steel, 440C stainless steel, and three levels of ceramic hybrid. All Enduro ceramic-hybrid bearings feature grade 10 Silicon Nitride balls (CH with chromium steel races, Zero Ceramic with black-oxide treated races, and lifetime-guaranteed XD15 super-stainless at the top of the line). Our bearings are always engineered with the deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements and to retain 90% fill of high-pressure waterproof grease.This ABEC-3 bearing features deep-groove design races, with Grade 10 balls, dual-lip, labyrinth, and LLB seals to withstand the daily abuse of use and the elements and contain the 90% fill Mobil XHP22 high-pressure water-proof synthetic grease.A radial bearing is generally used as a hub bearing and can be used as a pivot bearing though the MAX-type version of this bearing is better suited for suspension use.The Enduro line of bearings is available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless balls. Our bearings are always engineered with the deepest groove races possible to accommodate the largest balls possible and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
