  • Bearing assembly with thermal compensation
    Patent number: 4473309
    Abstract: Bearing assembly intended for operation in a given temperature range has a radially outer bearing member 16 made of steel and supported in a housing 20 made of a material, e.g. magnesium whose coefficient of thermal expansion is substantially higher than steel. The member 16 has radially inwardly facing surface 17 adapted to engage a radially outwardly facing surface 22 of the housing. In use, when the temperature of the assembly rises the surface 22 of the housing moves toward the surface 17 of the member 16 so that engagement between the surfaces 17,22 is enhanced or an initial gap 23 between the surfaces 17,22 is closed.
