A Pillow Block Bearing, also known as a plummer block, is a mounted bearing unit used to provide support for a rotating shaft with the help of compatible bearings and various accessories. It typically consists of a housing made from cast iron or stainless steel and a sealed ball bearing that sits inside. Designed for easy installation and maintenance, pillow block bearings are commonly used in industrial and agricultural machinery to reduce friction and support heavy loads. Their durable design ensures long service life even in harsh working environments.
