Broad, Double-Row, ABEC-3, Radial Bearing, featuring 52100 high-Carbon Chromium alloy races paired with grade 10 Balls. Used by Industry Nine in their rear hubs, and by Trek and Niner bikes for suspension pivots. The broad, double-row design minimizes flex in the axle of the rear hub or suspension linkage, precisely occupying the space of two 6803 single-row bearings. This ABEC-3 bearing boasts deep-groove races, Grade 10 balls, LLB seals, and 90% fill with high-pressure waterproof grease for daily use and elemental resistance. The Enduro line of bearings is available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD15 with ceramic or stainless balls. Our bearings are engineered with the deepest groove races to accommodate the largest balls and feature dual-lip seals creating a full labyrinth for superior protection against the elements.
