The difference between the maximum and minimum size limits of a part. The ISO system for tolerances on linear size provides ixo system of tolerances and deviations suitable for features of the following types:. Sliding fit not intended to run freely, but to move and turn freely and locate accurately. Whenever possible, selection of tolerance class shall be done among these tolerances to avoid too many numbers of tools and gauges. For simplicity, and also because of the importance of cylindrical workpieces of circular section, only these are referred to holed.
