B 542/F 2RS MAX - ABEC 3 MAX (Radial) - 1 5/16x1 3/4x9/32"

B 542/F MAX - MAX-Design, Flush, ABEC-3, radial suspension bearing - 1 5/16 x 1 3/4 x 9/32 Enduro Bearings pioneered MAX type bearings almost 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 providing greater lateral support for the twisting and multi-directional forces associated with mountain bike pivots. This ABEC-3 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. Unlike other B 541 bearings this Flush version does not have any extended inner races. This bearing has been used as a suspension pivot bearing in the past by 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.
