Sealmaster NP-20 Pillow Block Bearing is a two-bolt base, cast-iron housing unit designed to accept a standard 1-1/4 inch bore NP Series bearing insert. This standard-duty, fixed (non-expansion) pillow block uses a 52100 bearing-steel insert with a black-oxide finish and includes a felt seal for basic contamination protection. The NP-20 designation identifies the unit as Sealmaster's robust, general-purpose shaft-supporting block for light- to moderate-load applications. Its rugged cast-iron housing provides rigid, reliable support for rotating shafts in machinery that requires a compact, durable mounting solution.
