18 mm roller dimension - grand shanks

[Richard Moody]

I would like to ask how that dimension is measured?  From the
center of the center pin down through the shank to the center of
the piece of wood that connects the roller to the shank?  (what do
you call that?)  Or from the part of the roller the jack touches,
the distance from that to the center of the center pin? .      I
wish I could draw it it would save 100 words.
    The issue might be the thickness of the roller vs the spacing
of the roller from the center pin.   you have to consider both  as
in  rollers of x circumference are spaced y mm from the c pin.
while rollers of z circumference are spaced w mm from the pin.
