1. A method for producing a plain bearing sleeve with a length (L) of the plain bearing sleeve, which is designed so as to be greater than an inner diameter (IDM) of the plain bearing sleeve, and with a wall thickness (D) of the plain bearing sleeve, which is dimensioned to be smaller than 8% of the inner diameter (IDM) of the plain bearing sleeve, comprising:
a) providing a sleeve blank, wherein at least three threaded holes are arranged on a first end face of the sleeve blank;
b) clamping the sleeve blank on one side at a sleeve outer diameter (HADM) at a first end of the sleeve blank associated with the first end face in such a manner that the sleeve blank is rotatable about a sleeve longitudinal axis (HLA), and machining a sleeve inner diameter (HIDM) of the sleeve blank to the dimension of the inner diameter (IDM) of the plain bearing sleeve;
c) screwing of the sleeve blank on the end face by means of the threaded holes in such a manner that it can be rotated about its sleeve longitudinal axis (HLA) and machining the sleeve outer diameter (HADM) of the sleeve blank, wherein the wall thickness (D) of the plain bearing sleeve is formed; and
d) clamping the sleeve blank on one side at the inner diameter (IDM) at a second end of the sleeve blank opposite to the first end, and cutting off a ring comprising the threaded holes from the sleeve blank forming the plain bearing sleeve with the length (L).
