A bushing includes a cylindrical bushing body with a lubricant aperture and a dry lubrication source. The bushing defines a main bushing bore therethrough along a longitudinal axis. The lubricant aperture is defined in the bushing body along an angle relative to the longitudinal axis. The dry lubrication source is disposed in the lubricant aperture. A variable vane system includes a cylindrical case, a plurality of vanes projecting radially inward from the case, and a plurality of bushings. Each vane includes a respective vane stem operatively connecting an end of each vane to the case. Each bushing is disposed on one of the respective vane stems between the vane stem and the case. The respective vane stem is disposed within the main bushing bore and each bushing is slidingly engaged with the case.
