Amana tools and Magnate (via Amazon) both offer a few 1/2" bore bearings. Whiteside seemed to have a wider selection. These look like possible sources once you know your target OD.

Obviously one parameter is the 1/2" ID. The OD can easily be determined from the solid metal rub collars, if you have them of course.

The Power Pro does have the Shaper speeds as either 9500 or 10,000 RPM's depending on the material.
As for the Shaper Spindles Ed gave some links but here is some of what I know about them. Recently there have been 3 Shaper Spindles available. Two were designed for use with the Speed Increaser and need an adapter to use directly on the Headstock's spindle. One has the standard Rub Collars (P/N 555463) and the other has the ball bearing Rub Collars (P/N 555472). The Shaper Spindle with the ball bearing Rub Collars has a smaller diameter threaded shaft at 3/8" instead of the standard 1/2" so it uses sleeves for the difference. The other current Shaper Spindle (P/N 555117) goes directly on the Headstock spindle and is the old 1/2" Universal Arbor (P/N 505505) with the Rub Collar set instead of the two machined washers and spacer. All three of these Shaper Spindles are shown in the picture below along with the two early ones dating back to the Shopsmith Model 10E.

I have the 555117 arbor with the solid metal rub collars and of course all my cutters fit it and it will fit directly to the quill spindle. I think I'll just try to source some suitable ball races, rather than buy a complete new arbor which would also require the router chuck, which I really don't need, as I have a separate router table.
One thing I have which is a slight mystery is a 'cap' that sits on the very top end of the arbor spindle, with the same thread of course and it has a hole in the top to take an Allen wrench. It's completely circular, so it's sides are smooth and I guess it could be used as a small rub collar, although I can't think of a use for a collar that small. I've never seen a cap like that listed for Shopsmith.
I have a similar "cap" that came with a Craftsman spindle a half century ago. It allows the shaper outer 'wings" to be proud of the arbor cap. . .

ID and OD are very important but thickness is important also. Too thick may not allow the arbor nut to thread on all the way.

Interesting.
I'm not sure why someone would have supplied that cap with the Shopsmith shaper arbor. I'll just keep it in case I ever need it.
The standard Rub Collars have OD's of 25/32", 1", 1-1/4" & 1-1/2" and the Ball Bearing Rub Collars are 7/8", 1", 1-1/4" & 1-1/2" OD. It is the different ID size needed, specifically for the 7/8" ball bearing Rub Collar, that makes the difference. The Ball Bearing Rub Collars all use the same 7/8" OD, 3/8" ID Ball Bearings with a sleeve on the outside for the larger diameters. It is interesting that the catalog page (linked below) for the Ball Bearing Rub Collars has the standard Rub Collar diameters not the ones advertised although the only difference is the small one. If I am doing my math correctly the depth of cut for the 7/8" Ball Bearing Rub Collar would be 9/16" as opposed to 19/32" for the standard 25/32" Rub Collar. Whiteside Machine Company was suggested and they have 3 of the 4 OD bearings (7/8", 1-1/4" 1-1/2") with 1/2" ID that could work as they are for Router Bits.
For those of you checking my math based on Shopsmith's 2" diameter Shaper Cutters.
1/2 the diameter of the 2" cutter - 1/2 the diameter of the 7/8" rub collar = depth of cut
1" - 7/16 = 9/16"

I haven't found a shaper arbor yet, but one of the ones that mount in a 1/2" chuck would be useful to use the shapers on a router. That would probably be preferrable to under table routing with the headstock for me. I'm beginning to wonder if I need the double tilt for anything else. The plan is to make a router table that mounts on the carriage in the drill press, and I have the regular tilt reversed and table adjusted for under table drum sanding on the sanding shorty. Maybe I should just use the double tilt on that so I can choose under table or over table easily.
I will say the double tilt makes it easier to service headstocks but the idea is not to have to do that so often.
