Fit Tolerance ISO

Limits, Fits and Tolerances Calculator (ISO System)

Fit Tolerance ISO - Limits & Tolerances Calculator

"Fit Tolerance ISO" is an Android app designed to calculate engineering tolerances for various mechanical components, including bearings and shafts. It adheres to ISO 286-1 and ISO 286-2 standards, providing size limits, deviations, and fit types such as clearance, transition, and interference fits based on user-defined parameters. The app offers a schematic representation of the fit and includes recommended tolerances and fits according to ISO and ANSI standards in its Supplements section.

App summary

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.
