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 radial 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.
Solid-Lube bearings feature a unique solid, lubricant-infused polymer that replaces the grease inside of the bearing, eliminating any space for water or dirt to gather inside of the bearing. This MAX-type, Black-Oxide, ABEC-3 bearing features 52100 high-Carbon chromium alloy races paired with grade 10 balls. Enduro engineers all of our radial bearings 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/LLB seal combination on these bearings utilizes a more protective gray LLU seal facing outward, towards the elements, to reduce contamination from water or dirt, while the lighter-contact (less seal-drag) black LLB seals facing inward keep the lube where it belongs. Black-Oxide/Magnetite coating provides an extra level of corrosion resistance and extended worry-free performance.
This size bearing has been used as a suspension pivot bearing by a number of bicycle brands.
This bearing is also commonly identified in the industry by these part numbers:
The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15 with ceramic or stainless balls. Our bearings are always engineered with deep groove races to accommodate the largest balls possible. All of our standard bearings feature dual-lip seals that ride in a micro-groove creating full labyrinth to provide superior protection against the elements.
