Angular Contact (AC) Bearings are a “cup and cone” assembly, where the two races sandwich the balls at a prescribed angle. This allows them to manage radial, axial and combined loads. AC bearings are ideally suited for preloaded applications such as bottom brackets and headsets. Because they can be preloaded, AC bearings allow for precise sideload adjustment, eliminating free-play or “slop” while still smoothly handling radial load. Whereas radial bearings at times only provide 50% ball-to-race contact, AC bearings promote 100% contact, with the balls held in very light tension between opposing angular bearing races. To double down on durability, Enduro AC bearings include larger balls that smoothly carry greater loads while eliminating headset rattle or the micro-slop in wheel hubs that can contribute to disc brake rub. Enduro AC bearings are used in headsets, bottom brackets, hubs and suspension pivots.
