1. Guiding and centering device for a forming tool comprising a first mold half and a second mold half which are guided by a guide between a closed position in which respective separating surfaces of both mold halves are pressed against one another, into an opened position and vice versa,
the guiding and centering device comprising a protruding guiding body formed as a circular cylindrical bolt provided at the first mold half, a guiding recess formed as a bush with a first circular cylindrical inner surface provided at the second mold half, and a rolling element cage with rolling elements inserted in rows, by means of which the first and second mold halves are guided and precisely centered in the closed position, wherein the rolling element cage is supported by the first circular cylindrical inner surface of the bush and positioned via a positioner in such a way that when closing the forming tool, at least during an initial engagement, the circular cylindrical bolt runs substantially simultaneously in a first row of rolling elements and a second row of rolling elements of the rolling element cage, while the first row of rolling elements and the second row of rolling elements pass over a head of the circular cylindrical bolt without contact.
