The Plummer Block, as known as (Split/Non-Split) Plummer Block Housing, which is an assembly comprising of a self-aligning ball bearing or spherical roller bearing placed in bearing boxes of various shapes, has a large load capacity and is easy to handle, therefore it is widely used in general industrial machinery such as conveyors.
Plummer Block Housings are manufactured from high-strength cast iron as standard but are also available in cast steel or spheroidal graphite cast iron. The housings have a re-lubrication facility and can be used with either oil or grease lubrication.
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.
