Sealmaster SPM-43 CXU Pillow Block Bearing

Sealmaster MP-43 CXU Pillow Block Bearing delivers solid, fixed shaft support with a 2-11/16 inch bore housed in a cast-iron two-bolt base. This medium‑duty unit from Sealmaster’s MP Series uses a setscrew locking collar and a standard felt seal, with an insert made of black oxide on cast steel to suit shaft diameters from 2.5 to 2.99 inches (bore precisely 2.6875 in). The MFG part number is 715101 and the unit weighs about 1.78 lb, facilitating straightforward mounting and alignment. The CXU variant is described as a non‑expansion (fixed) bearing and is commonly configured with a seal flinger and GoldPlex‑HP grease for durable lubrication in challenging environments. With its cast‑iron housing and 2‑bolt base, this pillow block provides reliable support for rotating shafts in machinery and belt‑drive setups, delivering robust performance where a compact, maintenance‑friendly bearing solution is required.
