A sealed rolling bearing has at least one bearing ring with an end surface extending radially thereabout and supporting a support surface that may be positioned to engage the end surface. At least one annular groove is provided in either the support or end surface, having a groove bottom in which an axially compressible sealing ring is assembled. The sealing ring is axially and circumferentially yielding and is arranged either against a radially inner groove wall inclined to extend radially inwardly the groove bottom, or against a radially outer groove wall inclined to extend radially outwardly to the groove bottom.

In a sealed rolling bearing with at least one bearing ring having an annular radially extending end surface, a support ring having an annular radially extending support surface adapted to be brought into operative engagement with said end surface, and a circumferentially closed axially elastic sealing ring inserted in an annular groove in one of said end surface or said support surface that is axially opposite the other of said end surface or support surface, the sealing ring providing sealing contact with axial prestress about its circumference between a bottom surface of said annular groove and the other of said end surface or support surface; the improvement wherein said the sealing ring is also elastically yielding in the circumferential direction, and the annular groove has a groove bottom and a radial wall that is inclined to the bearing axis and extends to said groove bottom, the sealing ring being elastically stressed against said inclined wall of the annular groove.
