💡 What is a flanged ball bearing insert used for in industrial conveyor and shaft support applications?

A flanged ball bearing insert supports rotating shafts and keeps alignment in line-mounted systems. It’s a handy component for replacing worn pillow blocks and upgrading linear slide units.

- Supports radial and light axial loads for conveyor rollers and shafts, ideal for sealed ball bearing setups - Mounts easily to frames with a 3-bolt PF7 flange, compatible with standard shaft sizes and linear slide unit assemblies - Low-maintenance option with contact seal and set-screw locking for quick field swaps and retrofit work
