摘要

The joint has a joint outer part (7) with tread profile pairs running parallel to a rotational axis (A). Roller elements (2) are insertable between thread profiles (8) from a front side (10) of the outer part, and stay in connection with the thread profiles. A bellow is provided at the front side of the outer part. A blocking unit (12) is provided at the bellow or at a bellow adapter. The blocking unit reduces cross-section of a free space in an area of the front side of the outer part in a mounting condition of the bellow. The free space is formed between the thread profiles.
