ENDURO 3901 MAX SEALED BEARING 12 X 24 X 10 ABEC-3 (SUSPENSION)
Enduro’s MAX® Full-Compliment pivot bearings are the most battle tested, OE spec’d MTB bearings in the world. By removing the bearing retainer and completely filling the bearing races with balls, load capacity is increased 35% to 40% which dramatically improves reliability and longevity.
The first Enduro Bearings bicycle product, MAX ® bearings were pioneered specifically to solve premature bearing failures in high-load, high impact, low rotational speed MTB suspension systems. To address this need, Enduro co-founder Matt Harvey drew inspiration from the full-complement design of massive mast-guide bearings found on forklifts. By eliminating the ball retainer from the bearing, space becomes available to add additional balls (aka full-compliment), which dramatically increases load capacity 35% to 40%. This also significantly increases bearing reliability and longevity. A plug-in innovation that fits within the same small footprint previously occupied by traditional retainer and plain suspension pivot bearings.
MAX® suspension bearings are filled with Enduro MAX ‘extra high pressure’ grease and represent today’s industry-standard among bicycle manufactures. Enduro also offers MAX angular contact type bearings in both sealed and greaseable versions. Take a look, they’re probably already in your bike.
MAX Science and Testing
Enduro’s MAX® line includes only the highest quality 52100 chromium steel and 440C stainless steel coupled with black oxide, heat and cryogenic treatments in a rigidly controlled manufacturing and assembly production environment. MAX bearings provide more lateral support and can more capably withstand the harsh twisting and multi-directional forces that mountain bike suspension pivots encounter every time the bike is pointed downhill.
Enduro has been supplying leading mountain bike manufactures with both standard MAX® and bespoke MAX suspension bearings in a variety of configurations for more than 25 years. In addition to countless hours of in-house design and lab testing, MAX bearings have been subjected to decades of real world testing in the worst conditions imaginable, resulting in the best validation possible: loyalty. Annually, over 10 million MAX bearings are spec’d in the finest mountain bikes made, including these leading manufacturers: Santa Cruz, Yeti, Evil, Pivot, Niner, Alchemy, BMC, Atherton, Rocky Mountain, Orbea and Canyon.
