Abstract

A two-stage sealing arrangement for sealing an annular gap between an outer bearing ring and an inner bearing ring of a rolling-contact bearing, includes a first sealing element securely fixed to the outer bearing ring and having at least one sealing lip supported against the inner bearing ring. A second sealing element is disposed at an axial distance to the first sealing element, thereby defining a circular ring shaped sealing gap in a radial direction for accommodating, at least partially, a sealing material.
