💡 What is a flange bearing used for in conveyor and linear slide unit applications? Flange bearings provide shaft support and alignment under radial loads, making them handy for conveyor drives and linear slide units where a sealed ball bearing is preferred. Quick intro: Key ways flange bearings help in equipment setups: - Support radial shafts and reduce friction in sealed ball bearing configurations for conveyors and linear slide units - Provide fixed shaft location and secure set-screw locking for reliable alignment in industrial machinery - Allow relubrication via an NPT grease fitting and protect the insert with contact seals and a slinger for longer bearing life
