Abstract

The shaft location involves a slide bearing (1) of porous sinter material in which a shaft (2) is located. The shaft is of zirconium oxide and has a predetermined axial contact surface length. The contact surface length is less than k cubed root(V), where k is a value less than 2/5 and V characterizes the volume of the slide beraing. The axial contact surface length is less than 4/5 of the shaft diameter (d) and is less than 1/3 of the radial outer dimension of the slide bearing (D). The internal diameter of the bearing bore (8) in the area of the contact surface length is less than the internal diameter of the rest of the bore.
