A unison ring assembly for an axial compressor casing comprises an unison ring (4) and at least three unison ring supports (5,6,7) being radial inwardly and equally spaced arranged along the circumference of the unison ring (4), wherein each unison ring support (5,6,7) comprises an unison ring bracket (8) attached to the unison ring, a slide bearing (14) to be sliding along a slide face (2) of the outer surface of the compressor casing (1) and a resilient member (11,12,18,19) being arranged between and coupled to the slide bearing (14) and the unison ring bracket (8), such that the unison ring (4) is rotatable around the compressor casing (1) by sliding the slide bearing (14) along the slide face (2) and to be centered free of clearance about the compressor casing (1), wherein the resilient member (11,12,18,19) is adapted to accommodate radial displacement of the compressor casing (1).
