3903 LLU - Double-Row, ABEC-3, Radial Bearing - 17 x 30 x 10mm
This bearing is primarily designed for older square-taper bottom brackets (BBs). Its double-row structure significantly decreases flex in BB spindles and doubles the bearing contact area, all while needing approximately 25% less width compared to using two single-row bearings. This ABEC-3 bearing showcases deep-groove design races, Grade 10 balls, LLU seals, and a 90% fill of high-pressure waterproof grease, ensuring resilience against daily use and environmental elements.
