How to make it work?
(OP)
Hi guys! I have a servo motor with 0.25" drivibf shaft and it needed a coupler that help to connect to a drive sprocket. Unfortunately the shaft from the drive sprocket (linear guide) is about 28mm. I cannot really find the coupler that fit this dimension and I am not sure the motor can drive such the guide also. Thank you if any one can help.





RE: How to make it work?
I remember one time a designer got Bayside to make a special $$$ adapter to fit a larger servo motor to a small planetary gearhead. It lasted almost a week.
That being said.....
You can make a reducing sleeve and press or loctite it into a coupling that will accept a 28mm bore.
You may be able to use a keyless connector, like B-Loc, and use it as the reducing sleeve.
You can turn down the 28mm shaft to 6mm and buy a standard coupling.
You can get a coupling manufacturer to make a special for you.
