How to select the correct MASTERDRIVE coupling flange?

To select the correct MASTERDRIVE coupling flange, match the coupling size (e.g., size 7) to your shaft diameter and keyway type. Verify the outside diameter (4 5/8 in) fits your housing, and ensure the maximum speed (5,250 RPM) exceeds your application's operating speed. Always confirm bore dimensions are inch-based and round keyed.
