Abstract
A roll-formed sliding surface bearing bushing is circular in an installed state and has a butt joint which extends throughout the width of the bushing and is closed in an installed state. To ensure a backlash-free bearing arrangement, the bushing has on its outside peripheral surface a trapezoidal profile, which includes an angle of 1.degree. to 30.degree. with the plane which contains the longitudinal axis of the bushing.
