Abstract
The invention relates to a sleeve bearing provided with lip seals, which are each integrated into front areas of the sleeve bearing particularly for use in rough mixed friction operation. The lip seals each consist of a holding part, a support part and a pretensioned sealing lip, which rests linearly on an associated shaft/axis in the built-in state. The holding part force-lockingly engages into an annular groove. A cavity, which is formed between the shaft/axis and the holding part or rather the support part can be filled with a lubricant.
