During the cryogenic shrink fitting process, the insert is cooled via exposure to a cryogen, typically carbon dioxide (solid or liquid) or liquid nitrogen in order to reduce its size through the contraction associated with reduced temperatures. A companion operation of heating the housing (or other part) that receives the insert is conducted to

mation. Shrink fitting is the method of employing a cryogenic agent to shrink the shafts, tappets, or sockets, etc. so that fittings can be achieved that are far more cost effective than those achieved by heating the external components like gear wheels, housings, etc. Liquid nitrogen shrink fitting is one of the safest methods of assembly.

6/23 · Liquid nitrogen shrink fitting is therefore a vital process for safely creating very strong interference fits between parts, in cases where pressing or heating them may cause

Shrink fitting can also be achieved via cryogenic means: cooling the 'inner' part using liquid nitrogen causes it to contract so it can be fitted into the 'outer' part, after which it expands as it returns to room temperature to form a tight interference fit.

Only one component is treated. It is cryogenically cooled to sub-zero temperatures, for example by dipping the component in liquid nitrogen (-196°C). Shrink

Our preferred method is to freeze fit using liquid nitrogen. However descriptions of all methods can be found in this section. Freeze Fitting. This is a fast 

When using liquid nitrogen as a coolant, a temperature difference of up to 200 oC can be achieved. In order to cool the inner part it should be kept in liquid 

It can be used as an alternative to conventional press fitting, or more likely, to permit a mechanical fit that otherwise could not be accomplished via the mechanical force of press fitting. In application, the insert is cooled via exposure to a cryogen, typically carbon dioxide (solid or liquid) or liquid nitrogen in order to reduce its size through the contraction usually associated

Mansfield Cryogenics Ltd offer a shrink fitting service using Liquid Nitrogen as a medium for freezing down components to -195C.
