A laminated sliding member 1 includes a base body 4 having one flat surface 3 which is circular in a plan view and a solid lubricant layer 5 adhered to the flat surface 3 of the base body 4 and having a sliding surface 2 which is circular in a plan view.

A uni-directional and multi-directional mechanical bearing suitable for supporting structures such as bridges comprises a removable cassette comprising a sliding layer composed of a low friction material such as PTFE. The removable cassette allows for the replacement of the sliding layer without needing to remove or replace the entire bearing. The bearing can be part of a kit that includes a replacement cassette having a varying thickness that corresponds to the uneven wear on the sliding layer of the removable cassette and compensates for an eccentric pressure on the bearing when under load.

Disclosed are a pot rubber bearing, an intelligent bearing and a bearing monitoring system. The pot rubber bearing comprises a top bearing plate, a steel pot, a rubber plate and a base plate, wherein the base plate is stacked with the top bearing plate or the steel pot. A pressure sensing unit is arranged between the top bearing plate and the base plate or between the steel pot and the base plate. The intelligent bearing includes a data acquisition unit, a data output unit and the pot rubber bearing, the data acquisition unit transmits the bearing pressure measured by the pressure sensing unit to the data output unit. The bearing monitoring system includes a data acquisition unit, a data output unit, a monitoring center and the pot rubber bearing.

A pot bearing is provided for absorbing rotations with little constraint, comprising a pot, an elastomer cushion accommodated therein and a cover projecting at least partially into the pot and supported on said cushion. The elastomer cushion is slidingly sealed off from the pot, around the edge beneath the cover by means of a circumferential inner seal, which consists entirely or at least primarily of acetal with a melt flow index (MFI 190/2.16) of less than 6 g/10 min.
