Perforated™-Sliding Bearing

The Perforated™ Sliding Bearing consists of several layers of elastomer and intermediate layers of weather-resistant steel, grade WTSt 52-3.

The top steel layer has an attached polytetrafluorethylene (PTFE) layer, which functions as a sliding partner with a glassfibre-reinforced plastic plate (PTFE/GRP sliding pair). In addition to the advantages offered by the PerforatedT Bearing, ST, the Perforated™ Sliding Bearing can achieve longer sliding paths. Restoring forces are minimised.


for components carrying predominantly static loads with the exception of larger component displacements
