Abstract

An improved clutch release bearing assembly includes a sliding sleeve providing first and second sliding surfaces respectively facing the bore of a bearing and a guide element extending through the bore, both surfaces minimizing binding, wear or excessive friction between the bearing and the guide element during relative reciprocal motion therebetween. The sleeve, preferably fashioned from plastic, finds particular utility in a clutch release bearing surrounding a transmission shaft retainer or quill tube. The length of the sleeve is such that the bearing may slide on an outer sliding surface for a predetermined distance.
