Abstract
A protection and seal member for rolling bearings, arranged to be interposed between the inner race and the outer race of the bearing in order to isolate the rolling bodies from the surrounding ambient by providing a seal between the said races. The main characteristics of the protection member consists in that it is configured like a ring and is made of an elastomeric material so as to be capable of being snap-coupled with the outer race of the bearing on which it is mounted, and exerting on the outer surface of the inner race and on the inner surface of the outer race a sealing action between the outer ambient and the cavity formed between the said outer and inner races.
