Thank you, very good and very helpful information.
I have one more question if you would maybe know… already asking arround but didn’t get answer.
I have already kuka kr30 zh30/45/60-3, please see picture below, but there is oil leaking. Also I have spare wrist, which is marked zh30/45-2.
Do you maybe know if 2nd fits in my robot? It is also little strange, cause my robot is kr30-2, so maybe the wrist was already changed in the past for newer version. I would like to know if wrists are changable physically, dimensions about tool corrections, gear ratio?
