Pillow Block

A pillow block usually refers to a housing with an included anti-friction bearing, wherein the mounted shaft is in a parallel plane to the mounting surface, and perpendicular to the center line of the mounting holes, as contrasted with various types of flange blocks or flange units.

Pillow block bearing units are usually a housed bearing with a machined mounting surface and are used in mechanical power transmission systems to support shafts and couplings. The shaft is parallel to the mounting surface and generally perpendicular to the mounting screws. They are a type of housed bearing unit. These could have different types of bearings such as ball bearing, cylindrical bearing, tapered roller or synthetic bushing.
