Abstract: An elbow joint of an industrial robot comprises a first arm part which is yoke-formed at the joint and an end of a second arm part located between the yokes. On the sides of the end of the second arm part which face the respective yokes, bearing seats are provided in which shaft journals are journalled. The shaft journals are connected together by a pull rod, which extends through the end and the shaft journals, and are received in, and extend through, through-holes in the respective yokes. The shaft journals are fixed to the yokes by means of nuts threaded onto the accessible part of the shaft journals on the opposite side of the respective yokes.
