Description
The Sealmaster Mounted Cast Iron Two Bolt Pillow Block Ball Bearing is a robust, ready-to-mount bearing unit designed for reliable performance in normal to medium-duty applications. Featuring a solid one-piece cast iron housing, this pillow block ensures maximum strength and rigidity. The bearing insert, crafted from 52100 bearing steel with a black oxide coating, provides excellent corrosion resistance and durability. It utilizes a setscrew locking collar or Sealmaster’s exclusive Skwezloc® concentric locking collar for secure shaft attachment, minimizing slippage. The unit includes felt seals to protect against contaminants and retain lubrication, with a relubricatable design for extended bearing life. The two-bolt base allows for straightforward installation, supporting radial or radial-and-thrust loads. With a wide range of bore sizes and configurations, this bearing is ideal for applications such as conveyors, industrial machinery, and material handling systems. Sealmaster’s innovative features, like the lock pin and dimple system, enable direct lubrication and prevent outer ring rotation, ensuring optimal performance and reduced maintenance.
