Abstract:
1. A sealing device for a radial bearing including an inner ring, an outer ring and rolling elements interposed between the inner and outer rings, the sealing device comprising: a slinger which includes a radially inner circumferential edge portion fit to the inner ring and a body plate for axially obstructing an annular opening formed between the inner and outer rings; and a sliding seal portion which includes: wherein the sub-seal lip abuts against the inner surface of the body plate by being elastically deformed such that a slide contact area between the slide contact edge and the inner surface of the body plate has a substantially annular band shape; wherein the sub-seal lip is elastically deformed so as to be inclined toward the axial base surface by a centrifugal force generated due to rotation of the outer ring, and wherein a radial width of the annular band shape of the slide contact area is reduced towards the slide contact edge with increase in the centrifugal force.
