An air riding seal arrangement comprises two components 8, 12 which are relatively rotatable so that aerodynamic forces causes a supporting air film to be generated between them. At least one of the components 8, 12 comprises a cylindrical surface 22, 24 provided with a rib 26, 28. The rib 26, 28 serves to restrict the flow of liquid, such as lubricant, deposited on the cylindrical surface 22, 24 towards the gap between the components 8, 12. The rib further serves to draw lubricant away from the gap by surface tension effects, when both of the components 8, 12 are stationary. |
