Abstract
A process for producing a sliding bearing bush in a cast component of lightweight metal, preferably a tensioning lever of a belt tensioner. The process includes the following steps: a die, which forms the seat for a sliding bearing bush to be pressed in and has radially outer groove drawing noses, is inserted into a lightweight metal pressure die-casting die. After the liquid lightweight metal has been injected into the lightweight metal pressure die-casting die and subsequently solidified, the die is then drawn out of the lightweight metal pressure die-casting die in such a way that an aperture, which has a groove profile, is formed as a seat for the sliding bearing bush to be pressed in.
