3902 LLU MAX BOSL- Solid-Lube, MAX-Design, Double-Row, Black-Oxide, Angular-Contact Suspension Bearing - 15mm x 28mm x 10mm

MAX Solid Lube suspension pivot bearings feature a unique lubricant-infused foam polymer injection molded into the bearing assembly, replacing traditional grease or oils typically found inside a bearing. The solid lube polymer fills the entire cavity of the bearing leaving almost no room for contaminants or moisture to penetrate and create friction. After 3 years of successful field testing in the harshest conditions, we can confidently back Enduro MAX Solid Lube, Black Oxide bearings with a two-year, all-conditions, no maintenance required warranty.

Enduro's all-conditions Solid Lube solution is comprised of two essential parts: a continuous microporous polymer and a proprietary lubricant containing special additives. As Solid Lube engages with the moving balls, the lubricant is transferred from millions of pores to the ball and race surfaces. As the bearing moves, temperature and pressure introduce a uniform and continuous lubrication film between all metal parts to minimize friction and extend bearing life. When bearing movement stops, capillary action returns the lubricant back into the polymers micropores where it is stored for future bearing movements.

Enduro Bearings pioneered MAX-type bearings over 20 years ago for bicycles to address the challenges associated with mountain bike pivots. MAX-type bearings provide 35-40% more load capacity than standard Angular-Contact bearings by utilizing a special design where the maximum number of balls are inserted into the bearing, via a custom ground slot in the races. The additional balls, combined with deep race grooves in these bearings provide greater lateral support for the twisting and multi-directional forces associated with mountain bike pivots.

This MAX-type, Black-Oxide, ABEC-3 bearing features Black-Oxide treated, 52100 High-Carbon Chromium alloy races paired with two rows of grade 10 Balls. All Enduro bearings are engineered with deeper grooves to accommodate the largest balls possible, providing maximum bearing contact area and greatly increased bearing life. Designed specifically for bicycle applications, the LLU full contact seals used in these bearings utilize a dual-lip labyrinth design to provide maximum protection from the elements. The Black-Oxide/Magnetite treatment provides an extra level of corrosion resistance, as well as an additional level of material normalization, for extended worry-free performance against wear and the elements.

This bearing has been used by Alutech Cycles as a suspension pivot bearing.

The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and CXD Nitrogen Ceramic. Our bearings are always engineered with deepest groove races possible to accommodate the largest balls possible and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
