Abstract
A sealing ring device includes a sealing ring and a mounting or carrier ring which are supported relative to each other and relative to a housing or further hollow shaft. Thus, two pressure members are inserted between the sealing ring and the carrier ring at locations which are displaced by about 180.degree. from each other. Further, two additional pressure members are inserted between the carrier ring and the housing, whereby these additional pressure members are again displaced relative to each other at diametrically opposite locations. Thus, the angular spacing between neighboring pressure members is about 90.degree.. This construction makes sure that any bearing play or clearance remains small and independent of any centering errors in the shaft relative to its bearing in a housing or in another hollow shaft.
