  • Pot-type bearing for constructions such as bridges or the like
    Patent number: 4928339
    Abstract: The width of a pot bearing seal (8) is restricted to a minimum in such manner that it seals off the gap (18) between the internal pot wall (16) of a bearing pot (2) and a bearing cap (4) of a pot bearing (14) while providing a minimum overlapping between the pot bearing seal (8) and the bearing cap (4), whereas the height of the pot bearing seal (8) is such that the cylindrical surfaces (22) of the pot bearing seal (8) abuts the internal pot wall (16) even when the bearing cap (4) is inclined with respect to the horizontal line. Hereby the wear of the pot bearing seal is considerably reduced.
