Graphite plugged bushings are a special type of bushing that is used in applications that need continuous lubrication, but donâ??t offer easy access for the lubrication to be added manually on a regular basis. This type of bushing is made with graphite impregnated into the small holes in the bushings surface. When in use, these bushings release the graphite, creating a film of lubricant to keep machinery running smoothly.
