Steel ball bearings, product manufacturers, GKGZ unidirectional sliding seismic steel ball bearings provided by Hao Tong Engineering Rubber Co., Ltd. Hengshui. Steel ball bearings, product manufacturers, GKGZ unidirectional sliding steel ball bearings are seismic Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) launched this new upgrade, the above picture is only for reference, please call this page Contact phone or on the picture to obtain the latest information, contact: Liu. In the design, the general requirements to use ball bearing at least 30 years or more actual foreign demanding, ball bearings, such as the use of substandard products, not in three to five years, ten years, we will be Problems arise when GKGZ unidirectional seismic activity in the long run steel ball bearings, will reduce the life of rubber bearings, and bearing damage occurs early, ball bearings causing economic losses, which is currently the ball bearing One of the main problems in the hope project uses two-way active seismic unit GKGZ steel ball bearings, not only as the main basis cheap to buy support. Installation and maintenance, the ball bearing installation and maintenance, but also affect the laminated rubber bearings use of effects and the key to life, ball bearings so the newly revised industry standards, increasing the number of requirements in this regard. If the installation is unreasonable, not the construction process, the construction process mishandled or branched cushion stone bearing beam bottom center of the plate and receiving seat centerline do not coincide and so on. After the ball bearing girder installation is complete, you may have a bearing bias goods appeared not meet the requirements of the initial shear deformation, which are a direct impact on the life of rubber bearings use of effects and, therefore, the construction must be ensure close contact with the two bearings, ball bearings and piers between, so bearing force uniform, does not allow partial pressure and the Void phenomenon. Ball bearings sometimes encounter construction is completed, the construction of temporary taken to prevent the displacement of a fixed set GKGZ Fixed seismic steel ball bearings, not timely removed, in addition, the construction process because the laminated rubber bearing considerable amount of installation work . Typically ball bearing factory inspection will be certified through the film, the use of rubber-bearing structural core material, the use of a new type of steel supports, is generally considered necessary for the pilot project, based on the performance requirements of the holder, the selected test items considered necessary pilot project, the chosen experimental conditions, and the ball bearing is assumed that the pilot project from the purpose and use, and to ensure the applicability of the safety-bearing viewpoint, by testing the characteristics of master thoroughfare adaptation is necessary its performance can generally be carried out to confirm the appearance and shape of the ball bearing assembly according to the size and shape of the basic prerequisite is to ensure the performance of ball bearings, which must be consistent with the design of the ball-type bearing design requirements of the inspection of the project and quality testing methods used accordingly.
