circular (pin) keys/keyseats
(OP)
Does anybody have any info on circular (pin) keys/keyseat standards? I have been told that they are stronger than the standard square type.

It requires axial access to at least one end of the hub/gear interface after they are assembled. I've never, ever seen it done on the separate parts, e.g. mill a half- round keyway in both hub and gear separately, and set up the tolerances on hub, gear and pin so it can be assembled and isn't loose.
I've never seen a standard for it. It's a simple quick way to key a >particular< pair of parts together without broaching or milling. It's basically impossible to do it with interchangeable parts, and I can't think of a reason why anyone would try.
It's not as strong as an equivalent Kennedy key (square key installed diagonally), for which there are standards, except to the extent that the outside corner of the Kennedy keyway would be a stress raiser.
Well, hold on a sec. I have seen a partially derivative assembly, a motorcycle disc brake assembly with six or eight half- holes in a flange on the aluminum hub and the inner radius of an iron brake disc, retained to each other >loosely< by short double- flanged cylinders. The assembly was clearly designed to allow the disc and the hub to move (and expand) independently of each other to allow for thermal expansion and 'float' of the brake disc. And to look 'zoomy'.
Stick to standard stuff unless that's impossible.

After my original post, I did a little search on the net and found two sites (below) with some info on what I am referring to, but could not find any info on standards.
