Introduction.
Laminated elastomeric bridge bearings 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.
High Damping Rubber Isolation Pad for Shock Absorption are finding ever increasing application in today’s construction industry-as local load carrying components.
Applications.
Laminated elastomeric bridge bearings can be used for steel structures, pre-cast concrete structures, standard concrete slabs, and anywhere needs vibratuin isolation. This type of pad 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.
Features.
High quality rubber materials
CR, NR, SBR, or EPDM as elastomeric material.
Strong steel reinforced plates
Steel platesunder strict ISO 9001:2008 accredited quality control standards.
Low friction coefficient PTFE
Virgin PTFE without regenerated or filler materials.
