MR 17287 LLU/LLB CN A5 - ABEC 5 (Radial) - 17x28x7

MR 17287 LLU/LLB CN - ABEC-5, Radial Bearing (CN Clearance) - 17mm x 28mm x 7mm This ABEC-5 bearing features deep-groove design races, with Grade 10 balls, dual-lip, labyrinth, full-contact LLU seals facing outwards to withstand daily abuse of use and the elements, and lighter-contact LLB seals facing inwards to contain the 90% fill Mobil XHP 222 high-pressure water-proof synthetic grease. CN clearance specification is best for looser press-fit bearing bores. Radial bearing generally used as a hub bearing, and can be used as a pivot bearing though the MAX-type version of this bearing is better suited for suspension use. 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.
