Perforated™ Sliding Bearing, Type Z
The Perforated™ Sliding Bearing Type Z 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 Perforated™ Bearing, Type Z, the Perforated™ Sliding Bearing Type Z can achieve longer sliding paths. Restoring forces are minimised.
for components carrying predominantly static loads to accept larger component displacements
