MR 18307 LLU/LLB A5 CN - ABEC-5, Radial Bearing (CN clearance) - 18mm x 30mm x 7mm -

This ABEC-5 bearing features deep-groove design races, with Grade 10 balls, dual-lip, labyrinth, full-contact LLU seals facing outwards to withstand daily abuse of use and the elements, and lighter-contact LLB seals facing inwards to contain the 90% fill Mobil XHP 222 high-pressure water-proof synthetic grease. CN clearance specification is best for looser press-fit bearing bores.

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 a full labyrinth to provide superior protection against the elements.
