press fit
Tight tolerance assembly
A press fit is a mechanical joint where one part is forced into another slightly smaller opening, held in place by friction rather than fasteners or adhesives.
The interference between the two parts creates a tight, permanent connection: The bearing was installed with a press fit into the housing.
Also called an interference fit.
As a verb, to press-fit is to join parts this way.
