Haichen Supply KLQZ Tensile Ball Joint Steel Bearings Tensile Ball Bearings Unidirectional Tensile Ball Bearings Price

Description :

　　Performance of KLQZ tensile ball steel support:

　　1. Capable of withstanding vertical loads

　　2. It has the performance of resisting vertical tensile force to ensure the upper and lower structures during vertical earthquakes

　　Construct without detachment

　　3. The performance of resisting horizontal force ensures that the structure does not fall off during horizontal earthquakes

　　4. Adaptable

　　Radial and circumferential displacement requirements

　　Characteristics of KLQZ tensile ball steel bearings: Compared with similar bearings on the current market, this product has been optimized in four aspects: material selection, construction, details, safety and economy. The main features are as follows:

　　1. Material

　　The main steel material of the support adopts Q345 hot-rolled steel plate instead of cast steel, which has more reliable mechanical properties; The wear-resistant material uses modified ultra-high molecular weight (UHMW-PE) instead of polytetrafluoroethylene (PTFE), which has low wear, low friction coefficient, and long service life.

　　2. Reasonably constructed

　　This product has optimized the structure of existing support products, resulting in a more reasonable design. The KLQZ tensile ball steel support is equipped with a pre embedded steel plate structure, which facilitates the installation of the support; The support adopts anchor rods, anchor bolts and concrete connections, which are reliable in stress and easy to maintain and replace; The one-way support adopts a middle guide rail structure, which makes the sliding of the support smoother.

　　3. Pay attention to details

　　The support adopts a new anchor bolt structure with stronger shear resistance; Add wear-resistant grooves on the concrete contact surface for more uniform force transmission; The use of a new type of dust ring for the support not only protects the rubber pad but also the wear-resistant plate, extending its service life; The anti-corrosion coating is designed according to the current "Technical Conditions for Anti corrosion Coating of Highway Bridge Steel Structures" (JT/T 722), and different coating systems are used according to different engineering climate environments and anti-corrosion years. The anti-corrosion performance is reliable and the durability is good.
