Pillow block bearings, sometimes referred to as plummer block bearings, are mounted bearings that are used to provide load support for a rotating shaft. Their mounting surface is on a plane parallel and offset to the axis of the shaft. Mounting holes or slots in the base or feet of pillow block bearings permit adjustment and easy mounting.


Pillow block bearings mount and supports a rotating shaft in a housing, typically made of cast iron or cast steel. The pillow block housing keeps the bearings in place for reliable and consistent performance. Flange bearings provide support for rotating shafts that run perpendicular to the bearing mount, and are available in 4-bolt or 2-bolt mountings. Zoro also has a super selection of standard V-belt pulleys, flange bearings, and V-belts too.A pillow block usually refers to a housing with an included anti-friction bearing.
