Blacked ABEC 3 radial MAX bearing with 15 mm inner diameter, 28 mm outer diameter, 7 mm thickness and double-lip type
sealing with strong contact, making a labyrinth seal.
Black Oxide MAX bearings which get an additional Fe3O4 Iron Oxide (Magnetite) treatment are corrosion resistant and 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. They 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 salt water resistant "CRC Marine High Pressure Grease" inside.
With the corrosion resistance close to stainless steel, but much better load capacity, Enduro Bearings think these are the best pivot bearings you can install.
ABEC 3 bearings use grade 10 Chromium Steel Balls and 52100 High Carbon Chromium Alloy Races.
The high precision balls are within 10/1.000.000″ round, twice as round as the industry standard, at it's highest level.
The alloy races are made from a 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. The riveted Steel Retainer stands for toughness, ABEC-3 tolerances and noise tested.
