Ball bearing, Hao-engineering rubber, composite ball bearing is provided by Hengshui HaoTong Engineering Rubber Company. Ball bearing, Hao-engineering rubber, composite ball bearing is Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) this year launched a 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. 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 directly included, its contents, based on the practical application and 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 ball bearings, which presses for ball bearings and not for mechanical testing and design, there are a lot of press in the 20th century highway ball bearings, 60 gqz series ball bearings 70 years of 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of time, a lot of things behind the series must be updated xqz ball bearings to reduce occurred during the test due to outdated equipment boiled unnecessary misjudgment, in the past there have been a result of the press, under the bearing thickness is too thin stiffness is not enough, the test itself is deformed affect the situation of the test structure, 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 test results correctly sex. Ball bearings using high-quality carbon steel or steel into the Forbidden City molding, foundry, casting, heat treatment, machining and surface treatment material. Common are spherical bearings, cylindrical children u Oh, cylindrical bearings, roller bearings, flat bearing, ball bearing rolling bearings and other types of drinking pot bearings, rubber bearings carrying capacity is relatively large but its structure size is relatively large, the amount of steel consumption and more, because of its just too large, sharp force transmission is likely to cause damage to the substructure, and easy to rust ball bearings, high maintenance costs, repair hinges difficult. Mechanically when the ball bearing structure to achieve load transfer capability, the level of mobile features and functions of the rotation early enough, compared with a more vertical stiffness rubber bearings and rotating big strong absorptive capacity, and other prominent features, single due to bearing the different types, there will be a problem in the first virtuous horizontal displacement direction and the rotational direction, while, due to the ball bearing to bear the rotation bearing function and the function of the horizontal movement of 米昂 Once damage occurs, or the problem of corrosion and only pretending to be will fail problem requires attention. Therefore, you must wear a support surface using corrosion-resistant materials and attention dust repellant.
