ABEC 3 radial MAX bearing with 15 mm inner diameter, 28 mm outer diameter, 7 mm thickness and low friction single-lip type sealing.
1ZS sealings are developed for Greaseable Bearing systems mostly found on suspension bikes, these bearings are 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 our specially designed "Seal-Shield". This Seal-Shield will not pop off from the grease pressure, but remains in place as the old grease passes past the sealing lip and is refilled with fresh grease.
MAX bearings are 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 Almagard Extra High Pressure Grease inside.
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.
