61801 LLB CN ABEC-5 Bearing (CN Clearance) 12mm x 21mm x 5mm

61801 LLB - ABEC-5 Radial Bearing (CN Clearance) - 12mm x 21mm x 5mm Radial bearing generally used as a hub bearing for some quick-release hub designs, pedals and can be used as a pivot bearing though the MAX-type version of this bearing is better suited for suspension use. This ABEC-5 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. CN clearance specification is best for looser press-fit bearing bores. The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD15 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.
