6903 LLB - ABEC-3 Radial Bearing (C3 Clearance) - 17mm x 30mm x 7mm 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. 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 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
