The SKF FNL518B is a one-piece cast iron flanged bearing housing designed to support compatible bearings on a 80 mm shaft. Its square flange has four attachment bolt holes, providing a secure mounting arrangement for industrial machinery.
The housing has a 160 mm bearing seat diameter, a 50 mm bearing seat width and a 105 mm bearing seat centre height. The attachment bolt holes are positioned at 170 mm centres.
The B designation identifies the through-shaft version. The housing is supplied with two low-friction double-lip seals, which help retain grease and protect the bearing from contamination.
Compatible tapered-bore bearings are mounted on the shaft using an appropriate adapter sleeve. The bearing, adapter sleeve and locating rings are selected separately to suit the bearing arrangement.
