Popis produktu

MR 18307 LLB A5 - ABEC-5, Radial Bearing (C3 Clearance) - 18mm x 30mm x 7mm This ABEC-5 bearing features deep-groove design 52100 High-Carbon Chromium alloy races, with grade 10 balls, dual-lip labyrinth (LLB) seals to withstand the outside elements, and to contain the 90% fill Mobilux NGLI 2 high pressure water proof synthetic grease. Radial bearing generally used as a hub bearing, as a bottom bracket bearing for some older square taper BBs, and can be used as a pivot bearing though the MAX-type version of this bearing is better suited for suspension use. Quite often this bearing replaces bearings marked 6903 in front hubs from DT Swiss, Giant and Bontrager, though the ID of this bearing is 1mm larger than a standard 6903. 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.
