Abstract
An actuation structure changes the orientation of a vane airfoil. A spindle is fixed to the airfoil such that when the arm turns the spindle, the spindle turns the airfoil, the spindle extends through a bore in the housing. A mount is between the spindle and the housing at the bore, with a metal wear sleeve pressed into the housing at the bore, such that it is part of the housing. A bushing is secured to an outer periphery of the spindle such that a bearing surface during rotation of the spindle is provided by an outer periphery of the bushing and an inner periphery of the metal wear sleeve. A seal is radially outward of the bushing with the seal providing an air seal between the spindle and the bore. A gas turbine engine is also disclosed.
