When your application requires a product different than Helical couplings you keep in your stock, you can make your coupling meets your need by using accesories such as Adapter Hubs, Bore Reducers, Shaft Collar-Clamp Type and Solid Couplings produced by Helical. Ce
Adapter Hubs are used when the shaft diameter used in your application is bigger than the allowed maximum bore diameter of the coupling which will be used.
If you have enough distance between two shafts in your application, Solid Coupling can be used to connect these two shafts which have the same diameter.
