SHRINK FIT


Meaning of SHRINK FIT in English

A fit between two parts which is very tight. The outer or encircling piece is expanded by heating so it will fit over inner piece. Sometimes the inner piece is contracted by chilling. As the two pieces reach operating temperature or room temperature, the outer piece shrinks and the inner piece (if it was chilled) expands. As a result, the two pieces fit tightly.
