3801 LLB - ABEC-3, Double-Row, Radial Bearing (C3 Clearance) - 15mm x 24mm x 7mm Double-Row Radial Bearing used as a rear hub bearing for some rear hub designs and can be used as a suspension pivot bearing on a few Pivot and Santa Cruz bikes, though the MAX-type version of this bearing is more appropriate for suspension use. This ABEC-3 bearing features deep-groove design races, with Grade 10 balls, and LLU seals give maximum protection against the elements, while keeping the 90% fill of high pressure water proof grease inside. 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. 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.
