The primary function of Elastomeric Bearing Pads is to provide a connection to control the interactions of loading and movements between parts of a structure, usually between superstructure and substructure. Bearing pads provide a uniform transfer of load from beam to sub-structure. The surfaces of the bearing are generally flat or cylindrical. To function, is placed in a housing, as it has no threaded portion to affix it to a component. Erosion damage : Removal of the overlay in strips caused when the oil supply pressure is low or rapid journal movements occur. A footstep or pivot bearing support shaft parallel to the shaft axis and the end of the shaft rests on the bearing surfaces. Without bearings, we would be constantly replacing parts that wore out from friction. Newest First; Oldest First ; Random; Recently Active; Post Answer. While radial bearings can carry loads measured in thousands of pounds per square inch of projected bearing area; thrust bearings can only support loads of a few hundred pounds per square inch.. An extension of the steam end bearing housing enclose the rotating components of the speed – governor system. Fatigue damage: The overlay becomes detached from the lining when the bearing load becomes too high. Casing sealing glands. There are no bearings, big end and small end refers to the ends of the con rod (connecting rod).
