bi-Trapez Bearing®

Unreinforced elastomeric bearing can be loaded irrespective of size, the material is quality controlled. bi-Trapez Bearings® are unreinforced profiled elastomeric bearings, available in four thicknesses.

They provide high isolation against structure-borne noise and vibration,are permanently resilient in the case of jammed structural members and transmit little or no shear forces when structural members move or are displaced; they are used for all types of static supports and impact sound insulation for stair cases as well as landing supports.

They are made of quality controlled elastomer on the basis of the synthetic rubber ethylene propylene diene monomer (EPDM).


For structural members subject to predominantly static loading, impact sound insulation.
