Heavy Duty Self-Aligning Pillow Block Bearing Assemblies (Type SA-PB)

Type SA-PB pillow blocks and flange blocks are a uniquely designed compact unit (patented) requiring minimum support space. These units are self-aligning, ruggedly constructed, and suitable for non-lubricated heavy duty applications. They are fitted with a variety of Metcar self-lubricating bearing grades.

There are 10 different sizes available for shafts up to 3-3/8. There are 2 standard bearing cartridge lengths available: A and A-Ext. Bearing length A is used for medium-duty applications, whereas bearing length A-Ext is used for heavy duty applications. They are available in stainless steel for corrosive applications.
