Ball bearings and horizontal bearing hinge ball bearing hinge non-slip direction shall not be less than 10% of the vertical bearing capacity, seismic bearing horizontal bearing capacity of not less than 20% vertical bearing capacity, and can withstand not less than vertical to the 20% uplift bearing capacity. Ball bearing hinge is not applicable temperature range, bearing physical and mechanical properties of materials used PTFE sheet, PTFE sheet PTFE sheet bearing use should be made with fresh, pure material molded, not Use cutting boards, you should not use recycled materials, back material embossed sheet, together on the average particle size PTFE sheet material shall not be greater than 50mm, molding pressure should not be less than the physical and mechanical properties 30mpa Teflon plate. Monumental steel elastic ball bearing hinge bearing ball joints used, the use of materials such as technical conditions are met adjustable ball joint bearing, tension and compression drink holder designed to be used on the bridge seismic zone basin seismic rubber bearings, spherical shock Supports and LRB, these are almost always the patented product, can be expected in the near future will be the effective use of bridge engineering, while monitoring the quality of bridge engineering work has also been strengthened, power ball bearing hinge Experimental study of the performance are emerging to make the bridge bearings and better meet the needs of highway bridge construction. Is the use of organic solvent degreasing solvent dissolution of grease on the oil and clear way, the ball bearing hinge applies only to a mild case of oil, commonly used in gasoline, acetone, benzene and other solvents, solvent toxicity, ease of ignition and except Oil is not very clean. Rust on ferrous metal rust rust usually by hand, mechanical descaling way scroll seismic ball bearing hinges, spray rust and chemical rust and other methods, and hand-seismic ball joint bearings, mechanical and general effect spray rust far from ideal, ball bearing hinges are in addition to items such as larger when it is difficult to clean, chemical rust is an oxide with an acid solution utilizing embroidered chemical reaction to dissolve the surface rust. Ball bearing hinge stripped in order to achieve the purpose of rust, collectively known as pickling rust, surface rust great good or bad influence on the durability of the coating, according to a large number of experiments abroad can show good or bad rust coating The age difference of more than four times the durability forest processing and anodized basic surface after degreasing and rust, generally can not immediately painting, in order to prevent re-rusting and improve the adhesion of the coating, the ball bearing hinge often used The method of oxidation of certain phosphate chemical treatment, making the basic surface to form a protective film.
