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. We accomplish this with a special design where the maximum number of balls are 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. LLU seals give maximum protection against the elements, while keeping the 90% fill of Almagard Extra High Pressure Grease inside.

Angular Contact MAX type bearings, in both sealed and greaseable types. These bearings are spec'd on some of the best mountain bikes available, and you can also get them from us for replacement, or for building your own custom mountain bike. Enduro supply to almost 100 companies with bearings of various designs. And work directly with frame builders to get every detail right.

  • LLU - Is a double lip seal making medium contact, and also rides in a groove making a labrinth seal (reducing friction for less rolling resistance

Grade 10 Chromium Steel Balls:

High precision balls are within 10/1,000,000″ round, twice as round as the industry standard, at it’s highest level.

52100 High Carbon Chromium Alloy Races:

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.

Riveted Steel Retainer for toughness, ABEC-3 tolerances and noise tested, C-3 or C-N Internal Clearance

Always install bearings by pressing on the outer race only into a housing

UPC = 811780023246
Precision Grade = ABEC 3
Inside Diameter = 12mm
Outside Diameter = 21mm
Width = 8mm
Seals or Shields = LLU = Full contact, dual lip seal riding in a groove on the inner race. With more sealing pressure, these are ideal for pivots or headsets that continually come in contact with dirt, sweat, and dust. The increased seal pressure and 2 lips help retain the 90% grease fill we use on these bearings to better displace any moisture and continually lubricate the balls and races.
