The invention relates to a spherical rolling bearing which comprises an outer ring with a spherical race track, an inner ring, a plurality of rolling elements between the rings, and seals on one or both sides of the rolling elements. The invention is characterized in that the seals are formed with a rim which can be snapped against the spherical race track and kept in an outer ring by means of this rim and a portion which clamps against the side plane of the outer ring. By this design there is no need for the outer ring to be provided with grooves for holding the seals.

Sealed spherical rolling bearing

The invention refers to a seal for self-aligning spherical rolling bearings. It is characterized therein that it incorporates two cooperating annular and mainly radially directed plates affixed to one ring each. One of the plates is equipped with at least one annular sealing lip, which exerts a mainly axial pressure against the second plate.
