FAQ
What is Fit Tolerance ANSI used for?
Fit Tolerance ANSI is used to calculate ANSI standard limits and fits for non-threaded cylindrical parts. It helps determine the precise tolerances for components like bearings, shafts, and housings based on the ANSI B4.1-1967 standard.
What standard does Fit Tolerance ANSI follow?
Fit Tolerance ANSI follows the ANSI B4.1-1967 (R2004) standard, which is based on inch units for calculating fits and tolerances.
What types of fits can Fit Tolerance ANSI calculate?
Fit Tolerance ANSI can calculate various fit types including running and sliding (RC), locational clearance (LC), locational transition (LT), locational interference (LN), and force and shrink (FN) fits.
Does Fit Tolerance ANSI support metric units?
No, Fit Tolerance ANSI specifically works in line with the ANSI B4.1-1967 standard, which is based on inch units for its calculations.
