Maximum number of balls with angular contact: the 7902 MAX bearings 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.

Choose between 2RS seal version (type 1) and 1ZS seal version (type 2).

- balls that roll on 15 degrees angular contact
- MAX = maximum number of balls, no retainer and fill slot for balls
- in general 35 % more load capacity than retainer type (standard) bearings, do not spin as smoothly
- 52100 high carbon chromium alloy races with heat treatment followed by triple cryogenic treatment (310° Fahrenheit (-190° C)), hardened to at least Rockwell HRC 62, polished
- 2RS: 2 rubber seals, one per side
- 1ZS: developed for suspension bikes, completely open on one side where the grease is delivered during service by a pump through a grease fitting; as the old grease is displaced, it is purged past the inside seal lip of a specially designed " Seal-Shield"
- grade 10 chromium steel balls = 10/1,000,000" tolerance of sphericity
- ranked ABEC 1 by Annular Bearing Engineer's Committee for noise testing, ID and OD tolerances and raceways are made to ABEC 3 standards
