How to select the correct MASTERDRIVE coupling flange size?

To select the correct MASTERDRIVE coupling flange, match the coupling size (e.g., 12) to your shaft diameter and torque requirements. Verify the bore type (round keyed inch) and outside diameter (10 in) fit your application. Ensure max speed (2,800 RPM) exceeds your operating speed. Consult a power transmission specialist for proper selection.
