Fit Tolerance ISO Pro vs CNC CUBE

Limits, fits and tolerances calculator has been developed to calculate engineering tolerances of inner and outer features of journal bearings, linear bearings, thrust bearings, bushings, ball bearings, roller bearings, housings, cylinder bores, drilled holes, linear and precision shafts, pistons, etc. The calculator works in line with ISO 286-1 (2010), ISO 286-2 (2010) and ANSI B4.2 (1978) standards which are based on metric units. According to the input parameters of nominal size and hole/shaft tolerances, size limits and deviations for hole/shaft are calculated and fit type is selected among the clearance, transition and interference fits. The schematic representation of the fit is also drawn. The preferred tolerances and fits advised by ISO and ANSI standards can be found in the "Supplements" section.
