Here are some sizes as the company doesn't seem to be reading the Revain add-on. They fit well in my old office chair application. see drawing. They taper from 0.88 at the top to 0.92 at the flange, which is 0.98. Overall length 1.72. The ID is written out. You have to hammer them in, but that's okay. Let's see how strong they are, but good so far.
