Plummer blocks and pillow blocks are critical components in mechanical systems, providing essential support for rotating shafts equipped with bearings. Plummer blocks, also known as plummer pillow blocks, are characterized by their sturdy construction, typically made of cast iron or steel, and are capable of accommodating heavy loads in demanding industrial environments. These blocks feature a housing with a spherical roller bearing, offering stability and facilitating smooth shaft rotation. They often include mounting provisions and sealing mechanisms to ensure easy installation and protect the bearing from contamination, enhancing longevity and performance.
