Clearance and Interference Fit
we can see that there will always be sufficient clearance for the shaft to interface with the hole. In such a scenario, we will have a clearance fit.
In the below image, the minimum shaft diameter is 49.8, which is larger than the maximum hole diameter of 49.5. Hence, this would be an interference fit.
Applications
In clearance fit, there would still be an allowance for two parts to move, such as in a door hinge.
In interference fit, it would be difficult to move (or remove) the two interfacing parts. Usually, a lot of force is needed to remove the two parts. Examples are shafts that are fitted through bearings, so that the shaft does not slip.
