How do I couple two D shafts?

Answer:We don’t have a standard D bore coupling because there isn’t a standard D shaft to manufacture to. We do make some specials for D shafting, however they are meant to fit an existing shaft within the design. What we recommend is using a set screw type coupling. The flat on the D of the shaft allows for a better connection than a standard round bore so a set screw coupling normally works fine. If the shaft is hardened you normally can’t use a set screw type coupling because the screw won’t be able to bite into the shaft so we recommend at that point going to a normal clamp style. The only potential issue is that there isn’t full surface contact between the shaft and the bore so you could lose some performance. As always, we recommend that you test, test, test before you put something out there into a production environment.
