61803 LLU/LLB C3 - ABEC-5 Radial Bearing (C3 clearance) - 17mm x 26mm x 5mm -

A 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. C3 clearance specification is best for tighter press-fit bearing bores.
