Enduro Bearings 3903 – 17x30x10/13

3903 LLU-E – Double Row, Angular-Contact Suspension Bearing – 17mm x 30mm x 10/13mm – This Double-Row, ABEC-3 bearing features deep-groove design races, with Grade 10 balls and full-contact, double-lip, labyrinth (LLU) seals for maximum protection against the elements, while keeping the 90% fill of Almagard extra high pressure grease inside. The double-row design greatly reduces flex in the suspension linkage while doubling the bearing contact area and the extended inner race eliminates the need for extra spacers to connect suspension linkages. This bearing is most commonly used as a suspension pivot bearing for Pivot Bikes. 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. Static load – 1214lbf / 5.1kN Weight – 28.3g
