Recently I have come across a 1.8Mod 30PA spline. Does anybody know, what standard is that, if any?
Thanks!

Hi Spigor

I believe its a special. designers mixing it up, hard to reverse engineer.
did you measure the major, minor, and the base pitch?
what application?

(OP)
Here are the measurements:
T=19
da=31.725 mm

Yes, it's an internal.
