The seal seals a seals a space between the cup and the trunnion and includes an elastomeric member, wherein a first rigid part of the seal has, in an axial section, a first arm and at least one second arm, which are connected by an intermediate section of the first rigid part. The first arm and the second arm extend from the intermediate section toward the rolling elements and the second arm abuts against the trunnion. The intermediate section includes a first region, which contacts at least one projection of a face surface of the elastomeric member or which provides a gap seal or a labyrinth seal with the at least one projection, and at least a second region, which contacts the face surface of the elastomeric member.
