  • Patent number: 6315453
    Abstract: With the invention liquid lubricated radial sliding bearings are shown, of which the bearing sleeve is elastically fastened in an outer part and forms an elastic journalling with a shaft part which can follow thermal heat expansions and inclined positions of the shaft to a limited extent. Because the bearing material is fastened in a bearing ring and the outer part is formed in a single part to a resilient ring and a support ring which has resilient support surfaces which are directed inwardly and at which the bearing ring lies under a bias force, elastic bearings for high and low temperatures and for differently corrosive lubrication liquids are possible with the same outer dimensions.
