Heavy Duty Self Aligning Four Bolt Flange Bearing Two Three Sixteen Inch Bore Cast Iron Housing Precision Ball Races Goes Hard On Daily Grind Built Like A Tank For Shops And Trucks

2-3/16 Self Aligning 4 Bolt Flange Bearing Unit
✔️ Cast iron housing, 52100 steel insert, set screw lock

This heavy duty four bolt flanged bearing mounts directly to flat surfaces using a solid cast iron base and precision alloy steel raceway. You will typically find these mounted ball bearing assemblies running smoothly on conveyor rollers, farm equipment, industrial fans, and pump shafts where steady rotational support matters most. Each pack includes one ready to install unit designed for shops and light truck work.

✅ Pillow block ball bearing with self aligning design handles minor misalignment without binding
✅ Solid cast iron housing provides rigid mounting points for shop and truck applications
✅ Set screw locking mechanism secures the inner race firmly onto shaft diameters up to size
✅ General purpose construction works best in dry material handling and packaging lines

💡 What makes a four bolt flange bearing handy for rough daily grind jobs compared to standard pillow blocks?
- The four bolt flange plate distributes load evenly across mounting holes so vibration stays low during heavy cycling
- Self aligning inner rings take care of shaft deflection or angle errors before they eat into seal life
- Set screw locks grip shaft edges tightly without needing complex adapters or heat methods
- Standard cast iron bodies stand up to routine shop dust while keeping replacement times fast
