Maybe.. can't tell much from the sketchy drawing.
The pins look like stops for the spacer tubes, to me (assuming no shoulder
on arbor shaft for the spacer tube to fit up to).. whereas Joe stated his
grinder arbor shaft does incorporate a shoulder.

OK, have a look at this:

This is a long-shaft buffer, it HAS roll pins. So maybe what it is is
something that's been converted or a special order item. Can't think
of another explanation. Looks like the pins drive the inner flanges,
then there's a pin that drives some sort of hub for each buffing
wheel.
