VexPro has the exact weights for all the common FRC bearings. I'm not sure what CAD program you are using, but you should be able to set weights independent of material.

For rotation speed I agree with asid61, too slow, you are going at about 1/2 the speed of MOEs modules (see my post history) and that works out to about 1.2 rotations/sec. I have heard some teams gear them as fast as 4 rps.

Also, if you wouldn't mind posting a cross section of the coaxial shaft, I'm always interested in seeing how people connect all the parts in this area.
