Enduro Bearings 61903 LLU/LLB C3 - ABEC 5

61903 LLB C3- ABEC-5 Radial Bearing (C3 clearance) - 17mm x 30mm x 7mm -A 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. 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. C3 clearance specification is best for tighter press-fit bearing bores.The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15 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.Static load - 308lbf / 1.37kNWeight - 15.86g
