Two extreme permissible sizes of a part between which the actual size is contained are called limits. The relationship existing between two parts which are to be assembled with respect to the difference on their sizes before assembly is called a fit.

When it comes to clearance fit, the minimum size of the hole is always greater than the … Webb13 juli 2024 · The difference between hole size and shaft size is called allowance. Allowance is used to explain the difference between clearance fit and interference fit. Positive allowance indicates the clearance fit whereas negative allowance in a fit specifies the interference or force fit.
