ABSTRACT:
In a universal joint a device is provided for sealing an annular gap between a laterally closed bearing bush of the joint and a pin on a spider located within the bush. A plurality of cylindrically shaped bearing members are located within the annular gap in the bearing bush with an annular stop plate positioned at the ends of the bearing members facing the open end of the bush. A combination support member and sealing member is located in the annular gap with parts of the support member extending through the sealing member for supporting the stop plate. The sealing member is spaced from the stop plate. The support member divides the sealing member into a first part located between the support member and the pin, and a second part located between the support member and the inside wall of the bearing bush.
