Zusammenfassung:A bearing for a turbomachine variable pitch stator vane pivot mounted in a bore of the turbomachine casing is disclosed. The bearing includes an inner bushing secured to the pivot and an outer bushing secured to the bore. An elastomeric material is inserted between the inner bushing and the outer bushing to allow the vane to pivot about its axis and absorb at least some of the flexing of the pivot at right angles to the axis. The design makes it possible to reduce bearing bushing wear.
