Product Description
Neoprene or natural rubber bridge elastomeric bearing
Introduction.
Rubber Bridge Bearing Pads is made of multilayer Neoprene/EPDM/natural rubber with or without sheet steel after inlay, conglutinate, vulcanization. It has enough vertical stiffness to support vertical load, and it could deliver the pressure of superstructure to abutment.
Rubber elastomeric bearing pad is finding ever increasing application in today's construction industry-as local load carrying components.

Applications.
Rubber Bridge Bearing Pads can be used for steel structures, pre-cast concrete structures, standard concrete slabs, etc. This type of bearing is particularly effective in the presence of camber and rotation causing high stress loading on the bearings. This type of bearings provide an excellent economic solution for applications where structure movements, longitudinal, transverse and rotational are small, provide vibration isolation and are generally simple to install.
