Abstract
An assembly comprises a stationary armature to be secured to a stationary support, a moving armature bearing a magnetic disk to be secured to a rotating support, and a seal. The seal covers at least part of an exterior lateral face of a seal support wall of the stationary armature. The seal has at least one dynamic sealing means for rubbing against the rotating support and a ferromagnetic annulus attracted toward the magnetic disk, due to a magnetic field developed by the magnetic disk, to bias the dynamic sealing means against the rotating support. The stationary support and the rotating support may be stationary and rotating rings, respectively, of a bearing, upon which the assembly is mounted.
