Some manufacturers products are exported to foreign countries, mechanical properties testing requirements for foreigners saw our detection equipment, are reflected too far behind, so this standard rubber bearings are also made, using computer controlled test equipment should be capable of automatically and continuously smooth loading, unloading, automatic collection of test data, automatically drawing stress-strain curve and print test structures. Ball bearings so you can minimize human interference during operation, to improve detection accuracy, even if the current detection unit does not have to cover some of the testing methods, but also raised the standard, if it works with such tension and compression testing equipment spherical bearing, ball bearing detection unit may send a corresponding detection methods of testing personnel qualification certificates to the factory supervision and inspection, this approach abroad is also permitted. Ball bearings and detection units should try to improve and update detection equipment to ensure the serious type, the newly revised industry standard correctness, law enforcement detection structure, on the mechanical properties of test methods, procedures, loading, unloading speed, calculation method Test discipline etc made clear that PQXZ tension and compression of spherical bearings -DX, hope detection units, engineering expression of self-checking test results according to uniform regulations. Thus everyone a very clear, the ball bearing to old standards is also required, but not all units unity, given the results of some hard to look to understand. The ball bearing on the mechanical properties of the test requirements supplement the two, one is the rubber bearing shear bond test, an aging mount shear-type test, which is judged good or bad performance ball bearings Important indicators. Ball bearings, will vary with the form of engineering structures continues to expand, its use will continue to expand the scope and with the progress of science and technology, new materials appear, process improvement and development PQXZ tension and compression of spherical bearings -SX, in the form of ball bearings are not limited to stroke the rubber material, while the use of other forms of elastomers, and construction will continue to emerge and develop, so consider using the formula, you should pay attention to new materials and new techniques for structural Latest products. Bearing ball bearing is mainly made of steel castings or steel processing, in the past, is generally used as a bridge abutment using a rolling ball bearing type test steel parts, swing and slide to accommodate the displacement and rotation of the bridge a. Rubber bearing structure according to its use and there are multiple types of bearing capacity is characterized by his ability, can use a variety of bridge displacement and rotation needs, and on the great rebates and a large displacement of the support beams and has a very negative rebates good use, before the 1960s, mostly small and medium-span bridges using steel bearing PQXZ unidirectional activity in tension and compression of spherical bearings, bearing large tonnage highway bridge now use pot, rubber bearing more, while the railway Bridges were widely used steel bearings, steel bearings are steel commonly used bearings and special bearings and so on.
