How to select a bellows coupling for keyed shafts?

Select a bellows coupling by matching bore diameters to your shaft sizes (e.g., 1 1/4 in and 1 in), verifying keyway dimensions, and ensuring the maximum speed (10,000 RPM) exceeds your application. Choose stainless steel for corrosion resistance. RULAND MANUFACTURING couplings offer zero-backlash performance for precision drives.
