STANDARD TOLERANCES OF SHAFT MISALIGNMENT 

This  chapter  provides  the  standards  alignment  tolerance  of  misalignment  for  standard 
industrial machinery with flexible coupling that can be used under condition only if existing 
in-house  standards  or  the  machine  or  coupling  OEM  have  not  given  any  blinding  values, 
and must not be exceeded.
