The present invention provides a sealing element for an air-riding seal system. The seal has a mounting portion for mounting on a rotor and a sealing portion having a sealing face for facing a second sealing element. A bridging portion is provided extending radially between the mounting and sealing portions. The bridging portion allows axial displacement between the mounting portion and sealing portion and/or angular variation of the sealing face relative to the mounting portion and may be a pliable/flexible membrane structure allowing said axial displacement/angular variation by flexing. |
