Abstract: A robot arm includes a plurality of links and a plurality of joints connecting the links for adjustment relative to one another. At least a first link has a first bearing pin, a second bearing pin located opposite the first bearing pin, and a second link connected in an articulated manner to the first link by one of the joints has a first bearing flange on which the first bearing pin of the first link is rotatably mounted, and has a second bearing flange on which the second bearing pin of the first is rotatably mounted. The first bearing flange of the second link has a circumferentially closed recess in which the first bearing pin of the first link is received, and the second bearing flange of the second link has a circumferentially open recess in which the second bearing pin of the first link is received.
