"Crush Height

In order to achieve a required contact pressure, the outside diameter of an engine bearing is produced greater than the diameter of its housing. Such installation technique is called press fit (or interference fit). The difference between the diameters is called interference.
The difference between the diameters affects the amount of elastic compression of the bearing installed in the housing, and determines the value of the contact pressure P of the bearing.
Since direct measurement of the bearing circumference is a difficult task, another parameter characterizing the bearing press fit is commonly measured - crush height.
Crush height is the difference between the outside circumferential length of a half bearing (one half shell) and half of the housing circumference [1] measured at a certain press load.
Fig.2 illustrates a device for measuring crush height."
