We have used these same encoders with Andy Mark gearboxes. While direct mounting might be o.k, there could be issues. Any Axial shaft movement or bearing eccentricity will put loads into the resolver.

We have had very good luck installing these resolvers on a 3D printed standoff bracket, and using a small section of surgical tubing to connect the resolver shaft with the 1/4 shaft on the AM gearboxes. We zip tie both sides of the surgical tube for insurance.

There are multiple sizes of surgical tube. I believe we used 3/16 ID and 5/16 OD, for a very tight fit on 1/4 shafts. If you use 1/4 ID tube I could see it slipping.

The resolver and standoff bracket combined would be shorter than the mounted CIM motor length, so you really don't save much space by direct mounting.
