## What is Fit Tolerance ANSI?

ANSI limits, fits and tolerances calculator has been developed to calculate 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.

ANSI standard limits and fits calculator works in line with ANSI B4.1-1967 (R2004) standard which is based on inch units. According to the input parameters of nominal size and fit type selection among running and sliding [RC], locational clearance [LC], locational transition [LT], locational interference [LN], force and shrink [FN] fits, size limits for hole/shaft are calculated.

The schematic representation of the fit is also drawn. This calculator is applicable to non-threaded cylindrical parts.
