Steel Bearing, Hao-engineering rubber, ball bearing cast by Hengshui HaoTong Engineering Rubber Company. Steel Bearing, Hao-engineering rubber, spherical bearings are cast Hengshui HaoTong Engineering Rubber Co. (www.htgcxj.com) launched this new upgrade, the above picture is only for reference, please call or pictures on this page contact telephone number, to obtain the latest information, contact: Liu. Press the ball bearing material and adapt to temperature divided by (1) at room temperature type ball bearings, chloroprene rubber production, which adapt to changes in the temperature range may not be used in place of natural rubber neoprene, are not allowed in the chloroprene rubber incorporated in natural rubber. (2) ball bearings: Should the use of natural rubber (NR) production, which adapt to a wide range of temperature changes. Fulcrum rebate bridge superstructure is 150 ~ 8000KN bridges, and more generally the use of rubber bearings. Ball bearings suitable for smaller and smaller displacement span bridge, a different plane shapes for different bridge span structure, namely orthogonal rectangle bearing bridges, curved bridge, skew bridge circular cylindrical piers supporting the bridge should be used seat. Ball bearings for large span, continuous multi-span bridges, Charpy and continuous slab structures such as large displacement of the beam, it can be used to push the small slider continuous beam and T-beam traversing the like used . Rectangular and rubber bearing applications are the same as ordinary rectangular and circular laminated rubber bearings. 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 spherical bearing cast, so when this amendment industry standards, in order to facilitate the application, the original "highway bridge plate rubber mechanical properties of the finished bearing detection rules "(JT3132.3-90) as" roads and bridges laminated rubber bearings "(JT / T 4-2004) standard normative appendix directly included, its contents, in the practical application based on the standards and consider appropriate adjustments were made to add, in order to better control the quality of products, determine product strengths and weaknesses. In the standard, the first spherical steel bearing damping testing equipment, testing instruments, testing personnel made better requirements. 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 resilient steel ball bearings, 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.
