Abstract
Abstract A clutch release for use in motor vehicle clutches or the like includes a bearing and means for mounting the bearing. The bearing has two races, one of which is engaged by clutch release means while the other race is acted upon by clutch operating means. The bearing is mounted in such a way as to provide for limited movement or displacement relative to the mounting means whereby automatic centering with respect to the axis of the clutch may be obtained. Means are operably disposed between the mounting means and one of the bearing races which permits said limited movement or displacement of the bearing while preventing rotation of the last mentioned bearing race.
