Hi Scott,
It appears the quick disconnect (QD) bushing is made to order. It is an interface to bore sprocket and pulley but just the bushing is what one needs, I think.
Try www.mcmaster.com and search on "split taper bushing". At the top of the page you'll see the quick disconnect bushing. Click on "additional information" and look at style SF. Its flange OD is 4 5/8 and can be ordered for bore sizes 1/2 to 2 1/4 with the standard keyway.

David -
The split-taper bushings listed by McMaster-Carr are just the adapters needed to couple a motor shaft of a specific diameter to a flanged hub that you would bolt the RSG rotor to. As far as I can tell, McMaster does not offer just a flanged hub with the correct female taper to accept the split-taper bushings.
They do offer hardened steel sprockets that accept the taper-lock bushings, but these are through-hardened and would take a lot of machine work (EDM & grinding) to remove the sprocket teeth and add the bolt holes for the RSG disk.
Or have you found something hidden in the McMaster catalog that would provide the complete solution for mounting an RSG disk directly to a motor shaft (3/8", 1/2", 5/8", or 3/4" dia)? 

Regards,
Scott Hanson

Gerry,

You can get these adapters from McMaster-Carr
or a local branch of an industrial supply
chain like Johnstone or Grainger. What you're
looking for is called a "split taper bushing".
