A Plummer block is a type of mounted bearing designed to provide support and secure positioning for a rotating shaft. The term ''plummer block'' is often used in the context of larger, heavier-duty applications. The bearing unit consists of a spherical roller or ball bearing and a housing, usually made of cast iron or steel. The housing has a mounting surface parallel to the shaft axis and is typically in a block or box-like shape, offering stability and support. Plummer block bearings are commonly used in heavy industries such as mining, steel, and construction where robustness and load-carrying capacity are critical. The housing often incorporates features like bolt holes and end covers for sealing and protection. These bearings are known for their ability to handle high loads, accommodate misalignment, and simplify the mounting process. The term ''plummer block'' is synonymous with ''pillow block'' in many contexts, and the terms are often used interchangeably.
