Enduro Bearings pioneered MAX type bearings over 20 years ago for bicycles to address the challenges associated with mountain bike pivots. MAX-type bearings provide 35-40% more load capacity than standard Angular-Contact bearings by utilizing a special design where the maximum number of balls are inserted into the bearing, via a custom ground slot in the races. The additional balls, combined with deep race grooves in these bearings providing greater lateral support for the twisting and multi-directional forces associated with mountain bike pivots.
This bearing has been used as a suspension pivot bearing by a number of bicycle brands including Santa Cruz, Transition and Rocky Mountain. This size bearing is also known in the bike industry by these part numbers:
