The SKF FNL511A is a one-piece cast iron flanged bearing housing designed to support compatible bearings on a 50 mm shaft. Its triangular flange has three attachment bolt holes, providing a secure mounting arrangement for industrial machinery.
The housing has a 100 mm bearing seat diameter and a 27 mm bearing seat width. The attachment bolt holes are positioned on a 170 mm pitch circle.
The A designation identifies the shaft-end version, which is supplied with a closed end cover. It also includes a double-lip seal to help retain grease and protect the bearing from contamination.
Compatible tapered-bore bearings are mounted using an appropriate adapter sleeve. The bearing, adapter sleeve and locating ring or spacing washer are selected separately to suit the bearing arrangement.
