Seismic steel ball bearings _ _ Hao-way seismic engineering rubber ball bearing steel sales provided by the Engineering Rubber Co., Ltd. Hengshui HaoTong. Seismic steel ball bearings _ _ Hao-way seismic engineering rubber ball bearing steel sales are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) launched this new upgrade, the above picture is only for reference, please call this page or contact phone picture on to obtain the latest information, contact: Liu. Ball bearing enhance product quality supervision is a very important task, by a nationally recognized testing unit to strengthen the authority of the laminated rubber bearing product quality testing room is very necessary, but the last layer encountered some testing unit, testing equipment itself incomplete, the ball bearing detection methods are not familiar, rubber bearing testing personnel untrained, affecting the test results, so that when this amendment industry standards, in order to facilitate the application, the original "mechanical properties of the finished laminated rubber bearing Highway Bridges Detection Rules "(JT3132.3-90) as" roads and bridges laminated rubber bearings "(JT / T 4-2004) standard normative appendix, which included a one-way direct seismic steel ball bearing sales, its contents, on the basis of practical application, and to consider appropriate adjustments were made to add standards in order to better control the quality of products, determine product strengths and weaknesses. In the standard seismic steel ball bearings, the first of testing equipment, detection means fixed steel ball bearing wholesale earthquake, inspectors made more demands. Ball bearing some laboratories, it is not for the press as a ball bearing mechanical testing and design, there are a lot of press in the 20th century, 60,70 obsolete equipment. Ball bearings in many places can not guarantee the accuracy of the mechanical properties of the test seat. So with the progress of time, a lot of things behind must be updated in order to reduce unnecessary equipment behind boiled misjudgment occurred during the test, in the past there have been a result of the press, under the bearing thickness is too thin, not stiff enough, the test their structural deformation of the circumstances test, in addition, the ball bearing carrier plate plane size is too small, spherical bearings size has exceeded the carrying board inch, resulting in local stress affect the validity of the test results. Once contact with skin, wash immediately should, if contact with eyes, rinse immediately with plenty of water and seek medical advice as soon as possible. Ball bearings should note that this product can be stored for six months at room temperature and normal dry ventilated conditions, rubber bearing non-shrink grout is configurable products, in addition to the company's products epoxy grout, Epoxy filling injecting slurry, non-shrink grout purple willow flat. Ball bearing details of these materials can be lit directly linked to a query on the website. Non-shrink grout scope and characteristics, non-shrink grout slurry ceremony which uses non-shrink grout non-ferrous materials, the use of ball bearing load requirements and welding engineering. Mechanical chassis, structural columns, prestressed truss, bridge bearings, track support and base anchors, etc., and has the following characteristics. Flow-type ball bearing good, good dimensional stability. Can control the swelling. No external chlorination, no rust, bleeding and other harmful metals.
