ABSTRACT:
A sealing device for a bearing between a rotor and a shaft comprises two annular discs mounted one on the rotor and the other on the shaft, and an annular brush screen having the filaments thereof compressed transversely between annular sealing surfaces on the two discs. The outer periphery of one disc has a flange which surrounds the brush screen, and the inner periphery of the other disc has a flange which projects through the bore of the screen, the discs co-operating to form a casing which encloses and protects the brush screen. The sealing device can be mounted on one of the bearing rings of a ball bearing to form a self contained bearing assembly.
