💡 What is a flange ball bearing used for in conveyor, pillow block, and linear slide applications? Flange ball bearings support and locate rotating shafts in compact mounts and are handy for light-duty machines. Here are common benefits and uses: - Secures shafts in conveyor rollers and pillow blocks for reliable rotation. - Drops into linear slide units and light machinery as an easy sealed ball bearing replacement. - Fast set-screw locking and pressed steel flange make field swaps quick and low cost.
