Explanation of terms for maintenance standard 1
The maintenance standard values necessary for judgment of products and parts are described by the follow-
ing terms.
1. Standard size and tolerance
q To be accurate, the finishing size of parts
is a little different from one to another.
q To specify a finishing size of a part, a tem-
porary standard size is set and an allow-
able difference from that size is indicated.
q The above size set temporarily is called
the “standard size” and the range of differ-
ence from the standard size is called the
“tolerance”.
q The tolerance with the symbols of + or – is
indicated on the right side of the standard
size.
a The tolerance may be indicated in the text
and a table as [standard size (upper limit
of tolerance/lower limit of tolerance)].
Example) 120 (–0.022/–0.126)
q Usually, the size of a hole and the size of
the shaft to be fitted to that hole are indi-
cated by the same standard size and dif-
ferent tolerances of the hole and shaft.
The tightness of fit is decided by the toler-
ance.
