Abstract
Abstract This invention consists of a plain bearing in which the bearing surface consists of or includes poly-phenylene sulphide to give good bearing properties and also because such linings can be bonded of backings to steel or aluminum or aluminum alloys with a bond that withstands hard operating conditions, for example changes of temperature and changes of shape and stress. The linear polymer can be cross-linked to a desired extent by appropriate treatment.
