High damping isolation rubber bearings, also known as HDR bearings, are products designed according to the national standard GB20688 for domestic high resistance isolation rubber bearings. They are made by adding various additives to natural rubber to improve its damping performance (increase hysteresis loss and reduce storage modulus), and then using this damping rubber to make a laminated product of steel plate and rubber that is similar to the structure of ordinary rubber bearings through thermal vulcanization.

Pot type rubber bearings are bridge bearings composed of steel and rubber components. It has the characteristics of high bearing capacity, large horizontal displacement, flexible rotation, light weight, and compact structure. It has the advantages of simple structure, low height, convenient processing, steel saving, and cost saving, making it a suitable support for large-span bridges. The basin support reaches a new height. The need for more modern bridges. It is the soul of the entire bridge. The design coefficient of the room temperature type movable support has been lowered from the original 4, which improves the service life of the support. The structural principle of pot type rubber bearing is that the rubber block placed in the sealed steel pot can bear the vertical load of the bridge with the reaction force generated under the three-way stress. At the same time, the elasticity of the rubber can meet the rotation of the beam end, and the horizontal displacement of the bridge superstructure can be completed through the free sliding of the stainless steel plate welded on the upper seat plate and the polytetrafluoroethylene.

Anti seismic spherical steel bearings can withstand tensile, compressive, and shear (lateral) forces. Under the action of huge random seismic forces, as long as the upper and lower structures themselves are not damaged, catastrophic consequences such as falling beams and frames will not occur. Therefore, they are particularly suitable for the fortification of high-intensity seismic areas and have the ability to withstand seismic intensity of 9 degrees. Capable of universal rotation and bearing, it can effectively meet the transmission, rotation, and movement requirements of the reaction forces generated by various loads on the upper structure, ensuring the concentration, clarity, safety, and reliability of the reaction forces. The anti-seismic spherical steel support has a high static stiffness, and under the huge self weight and inertial force of trains and large vehicles, the support only produces very small deformation, which can reliably ensure the smoothness of high-speed operation of cars and trains. Suitable for a wide temperature range (-40 ℃~70 ℃), with good durability. Rubber is not used for pressure bearing, and there is no impact of rubber aging on the rotational performance of the bearing.
