A self-lubricated pressure plate or journal for use in supporting relatively slowly moving heavy loads of the type imposed, for example, by long structural members such as beams which expand and contract under temperature changes. A fabricated sheet made of material which has the inherent capability of lowering the coefficient of friction as the pressure thereagainst is increased, rests against a first plate of novel surface configuration whereby the sheet, when under pressure by a smooth second plate, will provide a suitable sliding surface for the second plate and will be effectively secured without bonding against sliding movement with respect to the first plate. The first plate has raised or depressed areas of controlled size against which the load acting through the fabricated sheet principally bears resulting in a controlled and lower coefficient of friction at these bearing areas. |
