F688 2RS - ABEC-3, Extended Race, Radial Bearing (C3 Clearance) - 8mm x 16/18mm x 5mm This ABEC-3 bearing features deep-groove design races, with Grade 10 balls, dual rubber seals and 90% fill with high pressure water proof grease to withstand daily abuse of use and the elements. The flanged design ensures precise insertion into through-holes in swing-arms and suspension linkages. This bearing has been used as a suspension pivot bearing. 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.
