Morphology

bushing = bush (opaque) = bush + ing

This is a regular suffixal noun formation, but the technical meaning is tied to a specialized sense of 'bush' that is not obvious from the everyday word.

Etymology

Bushing comes from the old word bush, meaning a little sleeve or ring put inside a hole to hold things in place. That's why a bushing is a lining that guides a shaft and stops parts from rubbing and wearing out.
