Sealmaster SPM-43 Pillow Block Bearing

Sealmaster SPM-43 pillow block bearing is a heavy-duty, two-bolt base mounting unit in Sealmaster's SPM series, designed to support a rotating shaft with a 2-11/16 in bore. The SPM designation identifies a robust, medium- to heavy-load bearing solution for industrial equipment, offering a rigid, self-contained housing that accommodates a standard Sealmaster bearing insert for reliable operation. The bore measures 2.6875 inches, enabling a shaft of that diameter to be securely retained by a locking mechanism—typically a setscrew—within the base unit. This configuration provides compact shaft support with straightforward alignment in machines such as conveyors, blowers, and other rotating equipment where space efficiency and dependable performance are important. Installation generally requires bolting the unit to a flat surface and maintaining proper clearance for rotation and alignment as part of standard maintenance practices.
