Product Details

Elastomeric Neoprene bridge rubber support bearing

Introduction.

Elastomeric Neoprene bridge rubber support bearing are 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.

Applications.

Elastomeric Neoprene bridge rubber support bearing can be used for steel structures, pre-cast concrete structures, standard concrete slabs, and anywhere needs vibratuin isolation. Plain and Reinforced Elastomeric bearings have become the most common type of bearing in recent years because of their desirable performance characteristics, durability, low maintenance requirements, and relative economy.
