Description
DR 21531 LLB – ABEC-3, Double-Row, Radial Bearing (C3 clearance) – 21.5mm x 31mm x 12mm –
Double-Row, ABEC-3, radial bearing with 52100 High-Carbon Chromium alloy races paired with grade 10 balls. The double-row design greatly reduces flex in the axle of the rear hub, suspension linkage or BB spindle 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.
This bearing is used in Zipp hubs, and some older Isis BBs.
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.
