Performance comparison of various couplings

my country's coupling products have now formed a three-category and multi-variety product system, and a large number of universal couplings have been formulated as national standards and machinery industry standards.Various couplings have their own different scopes and applications. Now we will compare the performance, characteristics, scope of application and applications with standardized and high-performance* couplings, so that users can choose from them according to their different requirements. For the coupling you need.
