ABSTRACT:
A spherical slide bearing having dust covers fixed by outer sealing collar portions interposed between a housing and a bearing or bearings. The interposed outer sealing collar portions of the dust covers are retained by flange portions of the housing and the bearing such that they are not forced out through narrow gaps therebetween through which bellows of the dust covers pass. Interference by the outer sealing collar portions with the degree of angular movement of a ball stud of the spherical slide bearing and damage to the dust covers is thus prevented. Tapered motion limiting surfaces incorporated into one of a ball stud, an inside bearing surface, and a ball stud and an inside bearing member surface provide an increased range of angular movement while protecting the dust cover from damage.
