Seal Master NP-23T BAS Pillow Block Bearing

The Sealmaster NP-23T BAS pillow block bearing is a standard-duty, two-bolt-base unit designed to support a 1-7/16 in bore shaft in light- to moderate-duty machinery. It features a cast-iron NP-T Series housing and a fixed (non-expansion) bearing arrangement for dependable, maintenance-friendly operation in industrial equipment. Key mounting and dimensional data include a base-to-bore centerline of 1-7/8 in, bolt-center-to-center spacing of 4-11/16 to 5-5/16 in, an overall length (OAL) of 6-9/16 in, and an overall height (OAH) of 3-3/4 in, with a two-bolt base that provides secure attachment to a flat surface. The BAS variant is intended for straightforward shaft support in conveyors, fans, pumps, and other light-industrial applications that require a compact, sealed pillow block for a 1-7/16 in shaft. As part of Sealmaster’s NP Series standard-duty line, NP-23T BAS combines simple mounting with reliable bearing performance for steady, economical operation in light loads and moderate speeds. It is compatible with standard 1-7/16 in bore inserts and common pulley and shaft assemblies, making it an easy drop-in replacement for older pillow blocks in compatible equipment.
