Web8 aug. 2015 · 3. 05-09-2014 3 Definitions • BASIC SIZE This is the size about which the limits of particular fit are fixed. It is the same for both “shaft” and “hole”. It is also called the “nominal size”. • TOLERANCE: Tolerance is defined as the difference between maximum and minimum limits of size for a hole or shaft. It is also the ... Interference fits, also known as press fits or friction fits, are fastenings between two parts in which the inner component is larger than the outer component. Achieving an interference fit requires applying force during assembly. After the parts are joined, the mating surfaces will feel pressure due to friction, and deformation of the completed assembly will be observed. Force fits are designed to maintain a controlled pressure between mating parts, and are used w…

The contact angle of a radial bearing under axial load is related to the radial play remaining in the bearing after installation. A higher assembled radial play means a higher contact angle. A low contact angle is desirable for pure radial loads.

WebAn interference fit (press fit & shrink fit) is a frictional shaft-hub connection. Joint pressure in the friction surface is necessary for the torque (force) transmission and this pressure is generated by the deformation of shaft and hub.
