Most of the times, a term may seem something which it is not. Shrink fitting may seem as if it is related to clothing but it is actually not!

Well, shrink fitting is actually a process of fitting one component into the other by the use of force or by expanding the component that’s at the outside by increasing the temperature.

The shaft-end is immersed into the liquid Nitrogen tank where the shaft is left alone so that it can cool down. The temperature in the Nitrogen tank is about -196 degrees centigrade. The shaft and the inner component, then warm up and expand to form a very tight fit. Retaining bolt is used to hold the sleeve together.
