[QUOTE 3688864, member: 9609"]nice quick and precise answer. thankyou.
So I presume the thickness of the sprockets and the holes and splines are all in the same place,
what is the difference between hg41 and hg50[/QUOTE]
Thickness of the sprockets are the same and the splines are the same, but the holes (presumably for the connecting pins?) may or may not be the same. I just don't know. Difference between 41 and 50? - I dunno.
