Abstract
A rolling bearing having an inner and outer race and at least one row of rolling members between the races, and sealing rings closing off the space between the races externally, each of which consists of an annular element of a rigid material, for example a metal, the outer edge of which is accommodated in an annular groove in the outer race of the rolling bearing and a sealing element, attached thereto, of an elastic material having a lip-shaped part which, with respect to the annular element, projects inward and rests against the inner race of the rolling bearing, characterized in that the annular element is a flat ring which closes off the space between the races, except for a relatively narrow slot between its inner peripheral edge and the inner race, and the sealing element of an elastic material likewise has essentially the shape of a flat ring, the outer peripheral part of which and the element of a rigid material are joined, so that the inner peripheral part projects outside the inner periphery of the rigid element, which projecting part is directed inward and the outer surface of which rests against the inner race, the length and/or the thickness of said abutting part bein…
