Pillow Block Bearings are bearing units that are contained inside a housing unit. The housing provides a rigid and secure positioning while allowing the bearing unit to rotate within a clean contained environment. The housing is bolted to a foundation allowing the outer ring of the bearing to remain stationary while the inner ring rotates. Housed bearings are generally used in light duty applications.

A pillow block bearing (or plummer block) is a pedestal used to provide support for a rotating shaft with the help of compatible bearings & various accessories. The assembly consists of a mounting block which houses a bearing.[1] The block is mounted to a foundation and a shaft is inserted allowing the inner part of the bearing / shaft to rotate.

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. A pillow block may contain a bearing with one of several types of rolling elements, including ball, cylindrical roller, spherical roller, tapered roller, or metallic or synthetic bushing. The type of rolling element defines the type of pillow block.

These differ from plummer blocks which are bearing housings supplied without any bearings and are usually meant for higher load ratings and a separately installed bearing. Plummer block bearings are designed for more corrosive environments.

The fundamental application of both types is the same, which is to mount a bearing safely enabling its 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 may be either split type or solid type.] Split type housings are usually two-piece housings where the cap and base may be detached, while solid are single-piece housings.] Various sealing arrangements may be provided to prevent dust and other contaminants from entering the housing. Thus the housing provides a clean environment for the environmentally sensitive bearing to rotate free from contaminants while also retaining lubrication, either oil or grease, hence increasing its performance and duty cycle.
