Abstract (en)
[origin: US4779842A] There is provided a height adjustable rubber pot bearing for supporting or lifting bridges. The pot bearing has an elastomer plate for transmitting and lifting or lowering loads wherein pressurized fluid is introduced between the bottom of the pot and the elastomer plate to displace the elastomer plate. A narrow slot is provided extending around the plate a small distance from and parallel with the inner side of the pot. The slot opens downwardly and has a depth of three-fourths of the plate thickness. A circular cylindrical insert is provided in the slot consisting of two parallel strips joined at their top edge with a space between them, the bottom edges of the strips being angled at right angles to form edge strips extending parallel with the bottom in opposing directions.
