Enduro Bearings F6800 – 10×19/21×5

F6800 LLU MAX BO – Flanged, MAX-Design, Black-Oxide, Radial Suspension Bearing – 10mm x 19/21mm x 5mm Enduro Bearings pioneered MAX type bearings over 20 years ago for bicycles to address the challenges associated with mountain bike pivots. MAX bearings provide 35-40% more load capacity than standard radial bearings by employing with a special design where the maximum number of balls (full-complement) are inserted into the bearing, via a custom ground slot in the races. The race grooves are also deeper on these bearings to provide increased lateral support to counteract the twisting and multi-directional forces associated with mountain bike pivots. This MAX-type, Black-Oxide, bearing features deep-groove design races, with Grade 10 balls and full-contact, double-lip, labyrinth (LLU) seals for maximum protection against the elements, while keeping the 90% fill of Almagard extra high pressure grease inside and Black-Oxide/Magnetite treatment provides an extra level of corrosion resistance and extended worry-free performance. This bearing has been used as a suspension pivot bearing by a number of bicycle brands including Trek. The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD15 with ceramic or stainless balls. Our bearings are always engineered with deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
