Guolis Enduro Bearings 6903 LLB ABEC 3

6903 LLB – ABEC-3 radial bearing (C3 clearance) – 17mm x 30mm x 7mm –

A radial bearing generally used as a hub bearing, as bottom bracket bearing for some older square taper BBs, and cane used as a pivot bearing, though the MAX-type version of this bearing is better suited for suspension use. This ABEC-3 bearing features deep-groove design races, with Grade 10 balls, LLB seals and 90% fill with high pressure water proof grease to withstand daily abuse of use and the elements.

The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid andD-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 superior protection against the elements.
