Limits, Fits and tolerancestolerance fits
interchangeabilty,asystem of Limits and Fits has been developed. While the system is used for all shapes and types of fit, the terminology uses a shaft and hole to define the principles. Some of the basic terminology is shown below in Fig 3. Fig 3: Terminology Types of Fit: A...

Reading A Tolerance is the difference between the maximum and minimum size limits of a part. The size of the object or its compound is called standard size, basic size, or design size. Tolerance refers to the difference between the maximum allowable shaft size and the minimum bore diameter. ...
ISO 286: ISO system of limits and fits. [1] This paragraph can be used to choose a fit and determine tolerances and deviations of machine parts according to the standard ISO 286:1988. This standard is identical with the European standard EN 20286:1993 and defines an internationally recognized...

5.13 Limits and fits It is impossible to make components the exact size and an allowance or ‘tolerance’ must be made which depends on the process and the application. The tolerance results in two extremes of size which must be maintained. The tolerances of two fitting parts, e.g. a shaf...
Limits and fits describe the allowance between the shaft and the hole. Allowance, in turn, is the maximum dimensional difference between the diameters of the two. There are three types of shaft-hole engineering fits. Clearance Fit This type of fit requires a shaft diameter to be smaller than...
