NKE has introduced the NNF series of compact, double-row, full-complement cylindrical roller bearings, sealed on both sides and suitable for extreme operating conditions. The series features maximum radial load-carrying capacity, which is accomplished through the full-complement design, that is, a maximum number of rollers is fitted within the available cross-section. The bearings are suitable for low to medium speeds in such applications as rope wheels and pulleys. Lubrication holes in the outer and inner ring enable easy re-lubrication.
