What are rubber bearings used for

Rubber bearings play various important roles in the engineering field, mainly including support, shock absorption, and deformation adaptation functions.

Firstly, rubber bearings mainly play a supporting role in construction and bridge engineering. It can withstand the weight of the upper structure, such as the self weight of the bridge span structure and live loads of vehicles traveling on the bridge, and evenly transfer them to the lower structure such as bridge piers and abutments, thereby avoiding stress concentration and damage to the lower structure.

Secondly, rubber bearings have significant shock absorption capabilities. Rubber bearings can absorb and dissipate some energy during vehicle operation, wind loads, or earthquakes, reducing the impact force transmitted to buildings and protecting the overall safety of buildings or bridges. Especially in earthquakes, the elastic properties of rubber bearings make them an important seismic isolation device, which can significantly reduce the damage to buildings caused by earthquakes.

In addition, rubber bearings also have the ability to adapt to deformation. It can adapt to structural deformation caused by factors such as temperature changes, concrete shrinkage and creep, ensuring the stability and safety of the structure. The ability to adapt to deformation makes rubber bearings particularly important in bridge engineering, as they can cope with small deformations caused by environmental changes and prevent damage to bridge structures due to excessive internal stress.

Finally, rubber bearings are easy to install and maintain. Its compact structure and lightweight make installation and maintenance costs lower, shorten construction time, and reduce the overall cost of bridge construction.
