According to your drawings, now pin shaft is stainless steel, carbon steel sleeve is.
Sleeve is in question, both ends of the wall thickness is too thin,
Only 1.23 MM, and carburizing layer depth is 0.7 ~ 0.9, it is easy to crack
Sleeve is can do though, but it's not the size of the reasonable design,
Will craze. Will give you trouble in the production
I want to ask whether drawing has been modified?
