Allowable de
eviations for diamete
ers
A difference
e is made be
etween inside
e diameter (h
hole) and outtside diamete
er (shaft).
Inside diameters are performed with
h plus toleran
nce (+) only and
a outside diameters
d
wiith minus tole
erance (-) on
nly.
As the plus tolerances (+) are correlated to the h
hole and the minus tolera
ances to the sshaft, the ran
nge of
tolerance iss reduced by half.
