Abstract: In a one-half part of a sliding surface bearing comprising a bearing half-shell (1) and at least one stop collar (2), the stop collar (2) constitutes a separate end flange and has mounting extensions (5), which protrude toward the bearing half-shell (1) and extends into fitting openings (3) of the bearing half-shell (1), which openings are open at the end face.To permit relatively large radii at the transition between the bearing half-shells (1) and the stop collar (2), the fitting openings (3) have an undercut (4), which is effective in an axial direction, and the mounting extensions (3) of the stop collar (2) extend behind the undercuts (4) and are axially aligned.
