Hao-engineering rubber | KZGZ seismic ball bearing hinge finished | seismic ball bearing hinge is 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 steel bearing brass ring opening by 2-3 layers rings, diameter steel pots and press molding, the site should be re-assembled brass ring excuse evenly arranged along the periphery of bearing steel pots, cross-sectional size and number of seals. Ball bearing hinge mainly commercial roof, PTFE slide, ball joints intermediate bearing plate KBQZ seismic wholesale, brass seals, rubber sheet, bottom basin, bolt, pillar, rubber gaskets and other components. Two months after passing inspection process but not assembled. Before the ball bearing assembly iron hinge pins on the Xiangjiang parts, burrs, oil sand and other debris cleared away, will be on the roof, under the bottom pots were painted and dried. KZQZ seismic bearing phone when assembling ball joints, ball joints bearing rubber sheet with Teflon first skateboard clean the rubber plate placed between the bottom of the tank basin, the basin should be evenly bottom layer of grease. After installing rubber sheet, rubber sheet suppliers favorite surface is also spread a layer of grease, then put in the middle plate, the director of steel on PTFE slide into the slot. And oil storage tank filled with grease (currently used grease) and then installed on the roof (in the assembly process at any time to clean oil and impurities, and strictly control the mounting accuracy of each component) of the total height of the last inspection bearing, ball joints When the holder of all packaging factory or warehouse to store after passing the ball bearing assembly hinge height deviation control in general vertical bearing capacity of less than or equal 2000kn, the deviation is less than 3mm, the vertical bearing capacity greater than 20000KN, deviation is less than 4mm appropriate, manufacturing processes ball bearing hinge products, ball bearing hinge basin child should do product requirements and general requirements for rubber block must do, are indispensable, the process summarized. In addition to stainless steel sliding surface, shall be regularly bearing steel paint anti-rust treatment. When connected to a bridge on the bridge bearings, it is important twisted point substructure, fine structure. Some call it the bridge lumbar spine, due to ball joint mount itself quality problems KZGZ seismic ball bearing hinge finished, and all sorts of improper design, installation, use the process, plus bearing atmosphere over many years in the wild images, ball bearing hinge most prone to the disease, resulting in premature bearing damage, it will seriously affect the normal use and service life of the bridge. Especially in some grain bridge built in the early, widespread loss of oxygen in a long time problem. Ball bearing hinge aging, steel corrosion failure, there are some small scissors span beam bridge originally did not support the setting of formal bearing. Making these bridges in the large tonnage, high traffic loads, there has been a series of problems, ball bearing hinge bearing an urgent need to carry out the replacement and maintenance.
