Has anyone ever done this assembly?
A double bearing assembly
I don't think they are exactly like the one you show, but there are a dozen or more in the library: https://grabcad.com/library?page=1&time=all_time&sort=recent&query=double%20bearing%20assembly
Did you have some question(s) about it?
yeah.. i just done it with the dimensions you have given..
