Steel structure supports can be divided into four types: GJGZ type steel structure shock absorption ball steel bearings, GJQZ type steel structure shock absorption steel ball bearings, GKQZ type steel structure earthquake resistant steel ball bearings, and GKGZ type steel structure earthquake resistant ball steel bearings. 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.
