That pretty much says it. I have a KR33 actuator which I am using for my Z axis. I'm using a Rex RS34-600 motor with a 1/2" shaft, and I need a coupling that will work with the KR33. The problem of course is that the KR33 motor mount is very limited in size, and most couplings are too wide and too long to fit in the limited space. I ordered a NEMA 34 adapter for the KR33, so I'm assuming there must be something out there that will work, but as yet I can't find anything. I'm thinking that the adapter will help to align the motor and the actuator shafts perfectly, so I don't thing the coupling needs to allow for any concentricity issues so it doesn't have to be flexible. Anti-backlash would certainly be a plus, but I'm not holding out hope...
Any help would be appreciated!
Thanks much,
