Sealmaster NP-20 Pillow Block Bearing 1-1/4 Bore

Sealmaster NP-20 Pillow Block Bearing is a rugged, two-bolt pillow block unit built around a 1-1/4 in bore insert bearing. Housed in a cast-iron body, this standard-duty Sealmaster unit is designed for fixed (non-expansion) operation, providing precise axial alignment and dependable shaft support in conveyors, fans, pumps, gearboxes, and other industrial machinery. The NP-20 family typically includes a ball bearing insert with a protective seal—often a felt seal—to help keep contaminants out while allowing for relubrication as specified by maintenance guidelines. Mounting is straightforward on a flat surface with its two-bolt base, offering broad compatibility with common 1-1/4 in bore insert bearings and a compact footprint suitable for space-constrained installations. Because Sealmaster is part of the Regal Rexnord portfolio, NP-20 housings are widely distributed through distributors and catalogs, including OEM and aftermarket suppliers, which helps with replacement and serviceability. This makes the NP-20 a durable, maintainable choice for light- to medium-duty shaft support, where a proven, ready-to-install pillow block bearing is essential.
