The shrink fitting process, is the method of using liquid nitrogen to shrink a component, so that it will fit into another component easily.

When the nitrogen affected component returns to ambient temperature, the component will expand to its resting dimension, enabling a perfect fit with its mating component. This process is ideal for components such as shafts, tappets, sockets, roller bearings. Any component that may require a calculated perfect fit.

Liquid nitrogen shrink fitting, is one of the safest methods of assembly as the the components will suffer no damage, unlike using heat.
