  • Height adjustable pot bearing
    Patent number: 4687182
    Abstract: A height adjustable pot bearing is provided having a pot, a steel cover plate and an elastic plate of substantially incompressible elastomeric material disposed in and completely filling the pressure chamber defined between the cover plate and the pot. A circumferential slot is provided in the base of the elastic plate radially inwardly from the outer wall of the plate so that a circumferential lip is formed. The pressurized fluid supplied to the pressure chamber of the pot bearing presses against the base of the elastic plate to lift the elastic plate and the cover plate and forces the circumferential lip radially outwardly against the wall of the pot to seal thereagainst.
