Sealmaster NP-30 Pillow Block Bearing One Seven Eighths Inch Bore

SEALMASTER NP-30 1-7/8" Pillow Block Bearing provides robust shaft support for industrial power transmission systems, featuring a cast-iron housing and a self-aligning mounted ball bearing insert that compensates for shaft misalignment while maintaining smooth operation. It is grease-lubricated, uses a contact seal, and employs a setscrew locking collar to secure the insert, with a two-bolt pillow block mounting. The bore diameter is 1-7/8 in, compatible with a 1.875 in diameter shaft, and the insert material is bearing steel inside a cast-iron housing. This bearing is designed for use in conveyors, agricultural equipment, packaging machinery, and material handling systems, and is also common in food processing equipment, fans, pumps, and industrial production lines where reliable shaft support and self-aligning capability are valued. The NP-30 is part of the SEALMASTER NP Series, with dynamic and static load ratings that are application dependent, and an industrial duty operating temperature range. Common replacements include Dodge P2B-SC-115, Timken PB Series 1-7/8" Pillow Block Bearing, and Browning VPS-230.
