Hao-engineering rubber | elastic damping displacement ball joint bearing | ball joint bearing displacement provided by Hao-engineering rubber. We are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) located at: Hebei Hengshui specializes in: grid bearings, bridge expansion joints, water stop, bridge bearings, rubber bearings, spherical stainless steel bearing plates is used as a two-way (or to) and one-way and one-way activity movable bearing slide bearing lateral sliders. Stainless steel pot bearings used material requirements are as follows: the requirement for stainless steel materials, chemical composition and mechanical properties which should be consistent with the relevant provisions of the steel surface shall comply with the requirements of the processing, surface hardness should be hv150-hv200 elastic damping displacement ball hinge bearing, coastal sea-crossing bridges and bridge bearings with stainless steel plate of choice, the length of monumental steel is generally less than or equal 1500mm, thickness using 2mm, stainless steel plate length greater than 1500mm, thickness using 3mm, stainless steel plate shall have a hierarchical way sliding displacement ball bearing hinges, surface defects may not have cracks, bubbles, impurities, scarring and other effects used. Stainless steel plate and grass surface after welding plane culverts shall not exceed the maximum deviation of the maximum size of the PTFE plate 0.03%. As the use of Teflon plate bearing activities, often using grease lubrication, at present, the use of 5201-2 standard bearing grease ball joints displacement, while the grease must be tested to ensure the bearing temperature range in use inside will not dry up on the slip surface material may not be harmful, and has good resistance to ozone, corrosion-resistant and waterproof performance. Its physical and chemical performance indicators should be consistent with the relevant provisions. Important part of the steel ball bearing hinge member, bearing bottom pots, plates and bearing on the middle of the roof is usually applied mold casting, machining tool path again to meet the design requirements. But also uses thick steel plate welded case processing, for which the relevant criteria are clearly stated requirements and make provisions. Rubber bearings caused by contact with oil to prevent aging, deterioration, skateboard bearings, pot bearing dust cover, should maintain good activity displacement shift ball bearing hinges to prevent the dust or rain falling, snow penetration bearings, different types of The holder of the conservation requirements, bridge bearings mentioned earlier, there are various types and forms, with different features, each bearing the conservation also have their own requirements. Note that in order to ensure and guarantee the normal function of the class after bearing do these requirements. Which is not due to bearing failure or damage caused by force to change the bridge, in order to ensure the normal use of the life of the bridge and the bridge. Laminated rubber bearing maintenance requirements, laminated rubber bearings in use, carry out regular maintenance and periodic maintenance style is very important work, but not usually think of it, the rubber bearings installed, you can ensure use.
