Abstract
A link rod with a U-shaped profile made from a one-piece sheet metal shell including two part shells and a back connecting said part shells. Bearing eyes are formed from a pair of aligned holes in the part shells. To obtain outer collars having inner bearing support surfaces for the bearing eyes with a slim-shaped construction of the link rod, the forming is performed stepwise by firstly producing the holes and bending the edges thereof to form the collars on one of the part shells which have not yet been brought parallel to each other by bending. Only then is what is to become the second part shell bent such as to be parallel to the first part shell. The holing and the bending of the edges of the holes on the second part shell is then carried out through the holes of the first part shell.
