ABSTRACT:
A joint bearing in which a rolling member has been designed in such a way that relative to the inner race track and outer race track representing a circular arch, four contact points are obtained, the rolling member is associated with a central cylindrical portion and carrying portions which adjoin it at both ends, and has an outer contour with a radius which is osculated relative to the inner race track and the outer race track, so that a relatively small and compact joint bearing is formed which permits both an angular movement and a rotational movement while reducing friction. The four-point contact permits accurate guidance of the rolling members and eliminates the need for guiding edges.
