Steel ball bearing steel ball bearing _13833855982_ unidirectional activities provided by the Engineering Rubber Co., Ltd. Hengshui HaoTong. Steel ball bearing steel ball bearing _13833855982_ unidirectional activity is Hengshui HaoTong Engineering Rubber Co., Ltd. (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. In addition, the ball bearing heavy cutting can be evenly distributed when the vehicle passes through the bridge horizontal force, absorbing part of the vibration, thus extending the life of the bridge, the general speculation about his life up to 35 years, at the same time, according to the information sphere steel unidirectional activity bearings, ball bearings also has a strong resistance to fatigue characteristics of steel ball bearings, bridge abutments not make due to fatigue damage under the action of seismic forces, in view of the above advantages and features rubber bearings, many advanced industrialized countries such as the United States, Russia, Japan, France, Germany, Canada and Australia and other countries have already comprehensive application, the ball bearings in the domestic engineering is the same as the above countries has been widely used, can be expected in the future laminated rubber bearing applications there will be further development of new and improved products will continue to appear on the market. Ball bearings from the case in recent decades for use on roads and bridges, in addition to the transportation industry standards set forth in the species, there were a few varieties of industry standards outside the so-called "non-standard" products, These products are in the technical reliability and maturity is also worth further exploration. Rubber bearings So, here the classification of the ball bearing manufacturing aspects only by the scope of the transportation industry standards, since the amount of ball bearings constantly increasing, more and more manufacturers, in view of laminated rubber support Block production process less complicated, many do not have the conditions of small factories or individuals can 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 two-way activity steel ball bearings, 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 material used for ball bearing steel ball bearing universal rotation, including rubber PTFE sheet to strengthen steel, stainless steel, grease oil quality requirements have been improved, as far as possible consistent with the foreign current levels. 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.
