Plumer Block also known as plumer bearing or pillow block bearing, is a type of bearing that supports a shaft and provides a means of mounting it within a housing. The housing is typically made of cast iron or steel and has a flat bottom surface for mounting on a flat surface. The bearing itself consists of a spherical bearing seat and a rolling element, usually a ball or roller, that is housed within the seat. Plummer blocks are commonly used in applications such as conveyor systems, agricultural machinery, and mining equipment.
