Seal Master NPL-36 Pillow Block Bearing 2-1/4 Inch Bore

Sealmaster NPL-36 Gold Line pillow block bearing is a fixed, low-base housing for a 2-1/4" bore shaft. The cast-iron body uses a two-bolt base and features a 2-11/16" shaft height to align with common mounting layouts. Inside, a 52100 bearing-steel insert finished in black oxide is secured by setscrews, delivering precise shaft location and durable wear resistance in standard-duty service. As a non-expansion (fixed) unit, the NPL-36 provides rigid support for rotating shafts where a stable, reliable 2.25" bore mounting is required. It is part of Sealmaster's Gold Line, a line of mounted-ball bearings known for robust construction and serviceability. This pillow block is suitable for new installations or replacements that require a proven 2-1/4" bore, cast-iron housing with a two-bolt base and a low-profile form factor, offering straightforward mounting while maintaining alignment over time.
