Enduro Bearings MR 18307 LLB ABEC 3 radial 18x30x7 hub bearing

Radial bearing generally used as hub bearing, bottom bracket bearing, for some older square cone BBs. It can be used as a pivot bearing although the MAX type is more suitable for suspension use. This ABEC-3 bearing has deep groove raceways, grade 10 balls, double seal insulation (LLU), and is 90% filled with high-pressure waterproof grease to withstand daily use and the elements.

This bearing often replaces bearings marked 6903 in the front hubs of DT Swiss, Giant and Bontrager, although the ID of this bearing is 1 mm larger than the standard 6903.

Enduro Bearings are always designed to accommodate larger balls and are double sealed to offer maximum protection against the elements.
