SKF/Global Needle Roller Bearings, with Machined Rings, with Flanges, with an Inner Ring - NKIS 17 146232018

SKF needle roller bearings with flanges on the outer ring and with an outside diameter up to and including 17 mm (Fw ? 10 mm), are manufactured with inserted closure rings. These bearings do not have a lubrication hole or an annular groove (fig). Larger bearings have integral flanges on the outer ring, an annular groove and, depending on size, one or more lubrication holes in the outer ring (fig). Needle roller bearings with flanges are generally designed as single row bearings. Bearings in the RNA 69 and NA 69 series, with an outside diameter ? 52 mm, have two needle roller and cage assemblies (fig). The outer ring and cage assembly of a needle roller bearing with flanges forms a non-separable unit.
