Enduro Double Row Bearing 3903 17 x 30 x 10

3903 LLU - Double-Row, ABEC-3, Radial Bearing - 17mm x 30mm x 10mm -

Primary application for this bearing is for older square-taper BBs. The double-row design greatly reduces flex in BB spindles and doubles the bearing contact area, while requiring roughly 25% less width than two single-row bearings.This ABEC-3 bearing features deep-groove design races, with Grade 10 balls, LLU 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 XD-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 a full labyrinth to provide superior protection against the elements.
