Pillow Bearing

A Pillow Bearing, also known as a plummer block, supports rotating shafts and keeps them fixed relative to a mounting surface. It consists of a housing, typically made of cast iron or steel, and an internal bearing, which can be a ball, roller, or plain bearing. Pillow block bearings handle radial and some axial loads, offer ease of installation and maintenance, and can accommodate minor misalignments. They are commonly used in conveyor systems, agricultural machinery, industrial machinery, and material handling equipment.
