Cuscinetto a blocco cuscinetto

Pillow block bearings, also known as plummer block bearings, are a specific type of Mounted Bearings commonly used as precision bearing components designed to house rolling bearings and support rotating shafts. Plummer blocks feature a base with mounting holes, allowing them to be securely bolted to a frame or other substructure. This design combines the functionality of a bearing with the stability of a bearing housing unit, eliminating the need for custom bearing housings. Consequently, Pillow block bearings provide a cost-effective and easy-to-use solution.
