Description

MR 18307 LLB - ABEC-5, Radial Bearing (C3 clearance) - 18mm x 30mm x 7mm -

This ABEC-3 bearing features deep-groove design races, with Grade 10 balls, light-contact, dual-lip, labyrinth (LLB) seals and 90% fill with high pressure water proof grease to withstand daily abuse of use and the elements.

A 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 standard 6903.

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 deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove creating full labyrinth to provide long life and superior protection against the elements.
