Maximum number of balls with angular contact: the 7901 MAX bearing by Enduro Bearings

Designed specifically for suspension pivots, Enduro Bearings pioneered MAX type bearings almost 20 years ago for bicycles to address the challenges associated with mountain bike pivots. These bearings have 35-40 % more load capacity than standard radial bearings. This is accomplished with a special design where the maximum number of balls is inserted into the bearing.
In standard radial bearings, only 3 or 4 balls make contact during the load, at any given time. In Angular Contact (A/C) bearings, ALL balls are engaged and spread the force over a larger surface area, to decrease friction and minimize wear. These bearings are engineered with a nylon retainer which diminishes rolling resistance and dual lip seals ensuring longer bearing life.
