Abstract

A bearing radially interposable between two relative rotatable parts such as the hub and friction disc or annular guide of a clutch plate for an automotive clutch. The bearing has inner and outer bearing surfaces each divided into at least two separate bearing zones. The inner bearing zones are angularly offset relative to the outer bearing zones. Relative radial clearance is defined by radial recesses between the bearing zones of the respective bearing surfaces which prevents additional friction developing between the bearing surface and the associated part and permits radial bending between bearing zones to compensate for limited axial misalignment between the parts. Cutouts in the rim of the bearing provide elastic deformation.
