The bi-Trapez Bearing® provides highly effective insulation against impact sound and vibrations and is permanently elastic in case of component rotation. This bearing is primarily used for structural members of all types and for impact sound mitigation in stair and landing components.
It is a non-reinforced elastomeric bearing with trapezoidal profiling on both sides and a shape dependent load capacity of up to 17.4 N/mm². The main component is an ageing resistant EPDM elastomer material with a hardness of 65 ± 5 Shore A. The material is weather and ozone resistant. The material is quality controlled.
