the quiet sleeve that lets metal touch metal without screaming about it
means A bushing is a removable cylindrical lining or sleeve fitted into a hole or housing to reduce friction, absorb vibration, or protect against wear between two moving or mating parts.
from From 'bush' in its old mechanical sense — a metal lining for a bearing or pivot hole — which English borrowed from Dutch 'bus' or Middle Dutch 'busse,' meaning a box, tube, or sleeve. That same ancestor is a cousin of the 'box' in 'box,' and ultimately traces back to Late Latin 'buxis,' a box made of boxwood ('buxus'). The '-ing' tacked on later gave the lining a workmanlike name of its own.
