6808 LLB - ABEC-3 Radial Bearing - 40mm x 52mm x 7mm This ABEC-3 bearing features deep-groove design races, with Grade 10 balls and full-contact, double-lip, labyrinth (LLU) seals for maximum protection against the elements, while keeping the 90% fill of Almagard extra high pressure grease inside. This bearing has been used as a freewheel bearing by White andustries and Burgtec. The size is also used by Pole Bike as a suspension bearing but the MAX-tyoe version is better suited for that purpose. 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.
