Elastic steel ball bearings _ _ Hao-seat Sales damper elastic support provided by the Engineering Rubber Co., Ltd. Hengshui HaoTong. Elastic steel ball bearings _ _ Hao-seat Sales elastic support damper is 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. Manufacturing, since the ball bearings in the constantly increasing amount of rubber elastic support, more and more manufacturers, in view of laminated rubber bearings production process less complicated, many do not have the conditions of small factories or individuals can be processed and manufacturing. But to really make sure that the product quality is not easy, because many factors ball bearing production, such as raw materials, including glue curing time, temperature and pressure. The revised industry standard when we try to consider the impact of various factors on the laminated rubber bearing product quality. Therefore, the main raw materials used in the ball bearing, including rubber PTFE sheet to strengthen steel, stainless steel, oil and grease are improved quality, as far as possible consistent with the current level of foreign. At the same time clearly defines the minimum amount of plastic containing not less than 55% by weight, emphasizing the incorporation of natural rubber, neoprene bearings, etc. are not allowed. Tolerances for processed products, the inherent quality and appearance also made better requirements to manufacturers to ensure product quality in the implementation of industry standards, so that the ball bearing manufacturer in the choice of the user, be sure to select the testing means complete, production advanced technology, high-level management, strong technical force manufacturers of products in the past have been found in the detection of plastic holder containing less than the amount of ball bearings and rubber layer thickness unevenness and cracks with steel from other issues, some of the mechanical properties of the finished product safety Zu not industry standards. 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 direct elasticity of steel ball bearing steel, its contents, in 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, first 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, 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 the elastic deformation of the case itself ball bearing steel test structure, in addition to elastic seat shock absorber, ball bearing bearing 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.
