BB 61803 LLU/LLB A5C3-blk | 17 x 26 x 5mm Bearing

61804 LLU/LLB CN- ABEC-5 Radial Bearing (CN Clearance) - 20mm x 32mm x 7mm Radial bearing generally used as a front hub bearing and has 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, dual-lip, 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 with high pressure water proof grease. 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.
