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 doubt that whatever you are trying to do will work. In the past when I have run into people trying to find coupling to directly couple a motor to a much larger pulley something is wrong in calculations.  My guess is at best you are going to have a large inertial mismatch which will make the system highly unstable.

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.
