To this end universal hinge support earthquake, when using structural separation type, the appropriate functional separation is necessary to ensure that the various rubber bearing structure is completed as expected, when the combination of ball bearings must meet the rubber support Block functions required to determine its structure and strength. Since each interaction between the upper and lower structure. Ball bearings complete and spread whining, after removing the old stand, the original beam bottom line carefully stainless steel rust and dirt thoroughly cleaned, coated with a layer of smooth oil. During an earthquake, the ball bearing off the beam due to the problem of the upper structure, must ensure that there is human life when falling beam damage accidents, while the bearing, the bridge should be controlled in accordance with an important bridge type, rubber ball bearings will not reduce the performance problem is also very important. Ball bearing type B bearing when using the most basic, but the constraints abutments in the upper structure is difficult to produce large vibration, even universal spherical rubber bearing steel bearing damage, less likely to be limited to off beam A class may also be a bridge abutment. Cumulative rock inside the earth so violently shaking motion, the ball bearing in the form of wave propagation caused the ground to the surface bumps and jolts. Due to the elasticity of the rubber bearing deformation and has good cushioning properties, so there is a certain seismic rubber bearing performance and better shock absorption cushioning effect in China since the 1960s began to develop steel sliding bearings, namely orthogonal rectangle bearing bridges, curved bridge, skew bridge pier bridge should be circular cylindrical bearings. It can be expected in the future application of ball bearings will further develop new and improved products will continue to appear on the market. The so-called "non-standard" products, ball bearings in the technical reliability of these products and the maturity is also worth further exploration. Ball bearing, and began sliding bearing steel has a trial in Guangdong, Shanghai, Shandong, Guangxi, Fujian, Jiangsu, Zhejiang and Anhui provinces section of highway bridge in 1995 | Chuzhou bearing | find bearings professional manufacturers to provide by Hengshui Hengshui Hao-Hao Tong Rubber Co. project.
