Extra-Wide, Double-Row, ABEC-3, radial bearing with 52100 High-Carbon Chromium alloy races paired with grade 10 balls. This bearing is used primarily by Industry Nine in their rear hubs. The extra-wide double-row design greatly reduces flex in the axle of the rear hub or suspension linkage while doubling the bearing contact area. 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.
