BB 688-A 2RS | 8 x 16 x 5/8mm Bearing

688-A LLB - Extended Inner Race, ABEC-3, radial suspension bearing - 8mm x 16mm x 5/8mm This ABEC-3 bearing features deep-groove design races, with Grade 10 balls and light-contact, double-lip, labyrinth (LLB) seals for maximum protection against the elements, while keeping the 90% fill of Mobil XHP 222 Extra High Pressure Grease inside. This bearing also features an extended inner race that eliminates the need for extra spacers to connect suspension linkages. This bearing has been used in the past as a suspension pivot bearing by Trek Bicycles. 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.
