@jthornton the hub mounts are available... some have threaded holes to bolt a sprocket...some do not have threaded holes...

Interesting, never searched for them so didn't know they existed.

You might also consider using a pull-pull system with cord attached to each side of the door. So this is just a spool mounted to the motor with two cords and a pulley on the other side. Turn the motor one direction and one cord winds up pulling the door while the other cord unwinds. Attaching the cords to the door at the bottom would prevent racking.

You can get XL series timing belt pulleys for metric shaft motors and use the timing belt as a pull-pull system.

Just wanted to post this here in reference to posts #14 , #92 , #95 & #96

Pull - Pull Door Opener basic setup with string but can be made with timing belt, timing gear pulley and two idler pulleys. Oh and this video I have the 5 Pin Window Switch I mentioned before in post #64.
