• a first component made of metal and having a hollow-cylindrical web section that extends axially, and the web section has a cylindrical inner circumferential surface;
• and
• a first bearing component made of a plastic material, the first bearing component being part of the two-part slide bearing, wherein the first bearing component has a cylindrical outer circumferential surface arranged on the inner circumferential surface of the first component in an interlocked, frictionally fixed, and/or material-bonded manner;
• wherein the web section of the first component has an axial front end face that extends radially outward from the inner circumferential surface thereof, and the two-part slide bearing has at least one flange that extends radially outward from the outer circumferential surface thereof;
• and
• at least a portion of the front end face of the web section abuts the at least one flange of the two-part slide bearing.
