61903/29.5 SRS | 17 x 29.5 x 7mm Bearing

63801 LLB - ABEC-3 Radial Bearing (C3 Clearance) - 12mm x 21mm x 7mm Extra-wide radial bearing used as a hub bearing for some hub designs, but more often is 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.
