ABSTRACT:
A device for eliminating the radial and axial play of a shaft having a circular ferromagnetic plate mounted thereon and which passes through a ferromagnetic stationary fitting. The device also includes a permanent magnet for establishing attractive forces within the device. A ferromagnetic arcuate part has a radius of curvature slightly larger than the radius of curvature of the circular ferromagnetic plate. The arcuate part is arranged in the proximity of the edge of the circular ferromagnetic plate whereby a first magnetic force acts between the arcuate part and the edge of the plate to eliminate the radial play and a second magnetic force acts between the shaft and the plate to eliminate the axial play.
