An arrangement for effecting a seal between components 10,12 that rotate together and between which relative radial movement is tolerated while maintaining the seal. A conical, or Belleville, sealing ring 25 is located between the components 10,12 and means 19,22 are provided for clamping the components 10,12 together. The sealing ring 25 is so shaped and dimensioned that, in use, centrifugal forces acting on the ring 25 impart a turning moment to the ring 25 to cause it to twist and effect a seal with each of the components 10,12.
