A sealing device composed of a lip seal and a spring or another resilient seal which radially and axially compresses the first seal, forming two sealing lines closed over substantially planar surfaces which are opposed in the direction of the protected rolling bearing axis. The device is small and lightweight and withstands the centrifugal forces in the lateral direction of the rolling bearing. It is possible to dispense with any further parts for retaining it. The space requirement is reduced, and assembly is easy. The sealing device is suitable for arrangements of variable-pitch propeller blade roots.
