Pillow block,also named plummer block or bearing housing,different brand called different name for this industrial part.Europe bearing manufacturer call Plummer block,FAG named Plummer block and pillow block,NSK and NTN say Pillow block,it is a pedestal used to provide support for a rotating shaft with the help of compatible bearings & various accessories,the pillow block housing material is typically made of cast iron or cast steel.
Pillow blocks usually refer to housings which have a bearing fitted into them and thus the user need not purchase the bearings separately. Pillow blocks are usually mounted in cleaner environments and generally are meant for lesser loads of general industry. These differ from "plummer blocks" which are bearing housings supplied without any bearings and are usually meant for higher load ratings and corrosive industrial environments. However the terms pillow block and plummer block are used interchangeably in certain parts of the world.
Pillow block bearing usually working with pillow block housing,FAG UC200,UC300 Series pillow block bearing,NSK UC series,and also some bearings working with plummer blocks like spherical roller bearings,self-aligning ball bearing,cylindrical roller bearings,deep groove ball bearings,The fundamental application of both types is the same which is to mount bearings safely enabling their outer ring to be stationary while allowing rotation of the inner ring. The housing is bolted to a foundation through the holes in the base. Bearing housings are either split type or unsplit type. Split type housings are usually two piece housings where the cap and base can be detached, while certain series are one single piece housings. Various seals are provided to prevent dust and other contaminants from entering the housing. Thus the housing provides a clean environment for the expensive bearings to freely rotate, hence increasing their performance and duty cycle.
