Tolerance class
Select the class of the tolerances.
This standard includes four classes of tolerances on space width and tooth thickness. This provides a range of tolerances for selection to meet a design need. The classes are variations of the former single tolerance which is now Class 5 and are based on the formulas shown in the footnote of Table 4. All tolerance classes have the same minimum effective space width and maximum effective tooth thickness limits so that a mix of classes between mating parts is possible.
For other tolerance classes:
Class 4 = 0.71 x Tabulated value
Class 5 = As tabulated in table
Class 6 = 1.40 x Tabulated value
Class 7 = 2.00 x Tabulated value
Fit class
Select the class of fit.
