Experience durable, maintenance-friendly mounting with the Sealmaster NP-23 two-bolt pillow block bearing, a cast iron housing delivering rigidity and reliable, medium-duty performance with setscrew locking for secure mounting in industrial use
✔️ Cast-iron housing with relubricatable seal, single-unit two-bolt base
The Sealmaster NP-23 Mounted Cast Iron Two Bolt Pillow Block Bearing is a rugged, ready-to-mount unit designed for reliable performance in normal to medium-duty applications. It features a solid one-piece cast iron housing for maximum strength and rigidity, and a 52100 bearing steel insert with a black oxide coating for corrosion resistance. This unit uses either a setscrew locking collar or Sealmaster’s exclusive Skwezloc concentric locking collar to secure the shaft and minimize slippage, with felt seals to keep out contaminants and retain lubrication. The relubricatable design helps extend bearing life, and the two-bolt base makes installation quick on conveyors, industrial machinery, and material handling lines.
