BB MR 17287 LLU/LLB A5-bag | 17 x 28 x 7mm Bearing

MR 19285 LLB - ABEC-3, Radial Bearing (C3 Clearance) - 19mm x 28mm x 5mm This ABEC-3 bearing features deep-groove design races, with Grade 10 balls, light-contact, dual-lip, labyrinth (LLB) seals and 90% fill with high pressure water proof grease to withstand daily abuse of use and the elements. A bit of an oddball size, this bearing generally used as a hub bearing, specifically for Fulcrum rear wheels. 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.
