Thoroughly made for high precision: the 6801 bearings by Enduro Bearings


Choose between ABEC 3 steel bearings (type 1) and MAX bearings (type 2).

ABEC 3 bearings by Enduro Bearings come with high precision balls that are within 10/1,000,000" round, twice as round as the industry standard, at its highest level. Vacuum de-gassed process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. Polished to a mirror finish for ABEC-3 precision and noiseless movement.

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. The race grooves are deeper on these bearings for more lateral support for the twisting and multiple forces associated with mountain bike pivots.

Features:


Type 1:
- ABEC 3 bearing with riveted steel retainer for toughness
- grade 10 chromium steel balls = 10/1,000,000" tolerance of sphericity
- 52100 high carbon chromium alloy races with heat treatment followed by cryogenic treatment (310° Fahrenheit (-190° C)), hardened to at least Rockwell HRC 62, polished
- LLB: most popular seal type, Nitrile material rubber with a steel insert; groove in the inner race where the seal can rotate (labyrinth seal), two razor thin sealing lips: the outside lip keeps the water and contaminates out, while the inner seal retains the grease
- ranked ABEC 3 by Annular Bearing Engineer's Committee for manufacturing tolerances and noise testing

Type 2:
- 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 cryogenic treatment (310° Fahrenheit (-190° C)), hardened to at least Rockwell HRC 62, polished
- LLU: dual lip seal riding in a groove on the inner race, more sealing pressure, ideal for parts that continually come in contact with dirt, sweat, and dust, 90 % grease fill (Almagard Extra high pressure grease)
- 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
