💡 How do I choose a flange adapter for sealed ball bearing and linear slide unit installations? Start by matching the shaft diameter and flange pattern to the bearing or slide unit you plan to use. - Match shaft size (1-3/8 in) and confirm normal wide profile for sealed ball bearing or pillow block compatibility. - Check four-bolt flange dimensions and mounting hole spacing against your linear slide unit or insert bearing. - Consider bearing style: sealed ball bearing for contamination protection or ceramic components for high-speed, low-friction needs. - Verify pack size (single adapter), material tolerances and mounting fit before ordering.
