Pillow-block-bearing Pillow Block Bearings Types. Each type of bearing has a different purpose, and is designed to best suit the applications and uses they’re needed for. Standard Ball Bearings: This type of bearing is made to be friction free, in order to perform at a high level while carrying large capacity loads.Extend the Life of Your Pillow Block Bearings The support bearings of literally millions of machines are located at or near the ends of the shafts so supported. However, design, configuration constraints or simple economics often preclude these support bearings from being fixed or rigid in the sense of being totally in line with each other.

Pillow block roller bearing units (also known as plumber block bearings) are mounted bearings and are designed for radial loads acting in the direction of the support surface (as opposed to a 2-bolt or 4-bolt flange unit). Components of a Typical Pillow Block Bearing. Standard pillow blocks from AST Bearings are made of the following components.
