Cylindrical roller bearing is a kind of modern machinery and equipment vital components

Bearing components are fixed and reduce the coefficient of friction in the mechanical load transmission process. When the other parts in the movement of the shaft relative to each other tapered roller bearings during the power transmission to reduce friction coefficient and to maintain a fixed position of the shaft center parts . Bearing is a kind of modern machinery and equipment vital components. Its main function is to support the rotating body for reducing the mechanical transmission device of the mechanical load during the friction coefficient .
China is one of the earliest countries in the world in our ancient invention Rolling constructed on the axle bearings has long been documented . Bearing is an important foundation for all types of machinery and equipment spare parts to its accuracy, performance , life and reliability of the host precision , performance , longevity and reliability play a decisive role . Bearing in mechanical products are precision products requires not thrust ball bearing only a comprehensive support mathematics , theoretical physics and many other disciplines and require materials science , heat treatment technology, precision machining and measurement technology , digital technology and efficient numerical methods and powerful computer technology and many other So bearing disciplines to serve on behalf of the National Science and Technology is a powerful product . Development momentum of China's manufacturing industry, a strong bearing on the smooth bearing steel market will bring positive effects to the good
