The SKF FNL511B is a one-piece cast iron flanged bearing housing designed to support compatible bearings on a 50 mm shaft. Its triangular flange provides a secure mounting arrangement for machinery where a conventional plummer block housing is unsuitable.
The housing has a 100 mm bearing seat diameter and a 27 mm bearing seat width. Three attachment bolt holes are positioned on a 170 mm pitch circle for mounting the housing to a suitable supporting surface.
The B designation identifies the through-shaft version. The housing is supplied with 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 ring or spacing washer are selected separately to suit the bearing arrangement.
