Elastomeric pad bearing


Elastomeric pad bearing


1.Codes for elastomeric pad bearing(China Standard JT/T4)

    For example,GYZF4300×54(CR) refers to a circular sliding PTFE bearing of 300mm in diameter and 54mm in thickness for highway bridges, which is a chloropene rubber(neoprene) bearing.

  The GJZF4 series and GYZF4 series sliding elastomeric bearings plate are made of  ordinary elastomeric pad bearings of which surfaces are bonded PTFE plates(thickness:2~4mm) equal to the bearings in dimensions.Besides properties of ordinary bearings , they feature in low friction coefficients(f≤0.08)between PTFE plates and stainless steel plates under beams so that the horizontal displacement of superstructure is not limited. Load classification:100KN-10000KN.
