Abstract
A bearing arrangement for supporting a universal joint trunnion in an outer cup includes a radial bearing having cylindrical rolling elements disposed between the trunnion and the outer cup, and a resistance member made of a material to allow elastic deformation and bearing upon a confronting surface area of an end surface of the trunnion. The resistance member and the trunnion are hereby so configured either alone or in combination as to form a large lubricant reservoir. Disposed at a distance to the end surface of the trunnion is a stop member to define an axial gap, whereby the stop member inhibits an axial movement of the trunnion after the trunnion has moved in axial direction to close the gap.
