about geometric tolerances

[chuny]

I have got the ANSI y14.5M. but I don't know what values of the geometric tolerances are proper to my pulley, shafts and other parts. Can someone tell me which standard I can use to give the value of geometric tolerances?
Thanks in advanced.

The geometric tolerances should come from the requirements for accuracy of your system design. You can look for similar designs for guidance. Nothing can replace experience.

Hi chuny,

Everything you ever wanted to know about standard pulley or sheave dimensions and tolerances can be found in Machinery's Handbook. These are derived from ANSI/RMA IP-20-26. I agree with israelkk. Prepare for a learning experience.
