Abstract: A sleeve bearing comprises two sleeves which are mounted for relative rotation one inside the other and which contact one another at radially outwardly extending flanges. The outer sleeve consists of rubber and has a sealing lip on its flange. The sealing lip reaches around the profile of the projecting flange of the inner sleeve and its sealing edge is resiliently biased against the outer end face of the inner sleeve flange. In addition to the sealing edge, the sealing lip can also have a sealing surface which, in cooperation with secondary machine parts, constitutes an additional seal for protecting the sealing edge.
