SpletThe FN4 fit is a “Force fit suitable for parts which can be highly stressed or for shrink fits where the heavy pressing forces required are impractical.” Excerpts from the ANSI B4.1-1978 standard are provided in Table A-1 of this tutorial. SpletOur Fits & Tolerances Calculator allows you to easily determine type of fits using the tolerances according to DIN ISO 286. In addition, upon entering the nominal diameter the tool calculates lower and upper limit deviations plus the maximum and minimum interferences dependent on the selected tolerance classes for bore and shaft. spartanburg habitat restore
