Natural Rubber bearing generally consists or interleaving layers of rubber bonded sandwich
fashion to steel plates. The whole unit is covered with rubber to afford weather protection.
A bridge basically consists of bridge deck supported by piers. In order to avoid over stressing and
damage by movements of vehicle and loading to the piers, bridge bearings are used to
accommodate these movements so as to reduce the reaction forces and bending movement to
within the safety limits of structure. Natural Rubber is an ideal engineering material for bridge
bearings as it is highly elastic and sufficiently soft to accommodate these movements without
transmitting harmful stress and also it can absorb and isolate energies from impacts and
vibrations.
Types of bearings
Laminated bearings – an elastomeric bearing containing steel laminates bonded to rubber
Plain pad bearing – a plain rubber pad containing no steel plates
Strip bearing – a plain pad bearing for which the length is much greater than the width ( > 10 times)
Pot bearing – a bearing consisting essentially of a block of solid rubber enclosed between a metal
piston and metal cylinder
