The app provides results based on the ISO 286 System of Limits and Fits, “ISO Fits & Tolerances," and is intended to help engineers better-use their time and work away from their desks.
ISO Fits & Tolerances is easy to use. After entering the nominal diameter needed, users simply select the tolerance classes for bore and shaft. The app then provides the complete ISO fits definition with all relevant values, including type of fit. Tolerances are shown for the most commonly used ISO tolerance classes and graphs illustrate these classes by bore and shaft.
“ISO Fits & Tolerances” is available in English and German free from iTunes or via the Apple App Store on the iPhone and iPod Touch. Search “Trelleborg ISO Fits.”
