Definitions:

Force And Shrink Fits

Describes a class of fits achieved by creating a size differential between two mating components such that the parts must be forced together, often involving heating or cooling to assemble.

Transitional Fit

A type of fit between two mating parts where interference may or may not occur, allowing for a balance between clearance and interference fits.

Clearance

The intentional space or gap between two parts or components, necessary to ensure proper fit, movement, or function.

Interference

A condition where two parts intentionally have dimensions that prevent them from fitting together unless deformation occurs, ensuring a tight fit.
