FNL 520 A SKF (replacing part no. 722520 A) 4 Bolt flanged housing

FNL flanged housings are non-split plummer block housings. The flanged bearing housing is a well-proven machine part and a simple solution for applications that do not have a horizontal frame. Yet simplicity is no reason to choose the cheapest solution. Material quality, precision tooled surfaces and careful mounting are just as important here as in any bearing arrangement. FNL gives you modern thinking and long-term functionality. The old felt strip is no match for a modern double-lip rubber seal that is easier to install and far more reliable. The new design keeps the grease securely in position and effectively shuts out all contaminants. What's more, the new solution allows rotation speed limits twice that allowed by a traditional felt seal. Up to 8 m/s.
