    The Development History of Bearings
        

                    
        
    One of the earliest countries in the world to invent rolling bearings is China, and the construction of axle bearings has been recorded in ancient Chinese books. From archaeological relics and data, it can be seen that the oldest bearing in China with the embryonic form of modern rolling bearing structure appeared in Xuejiaya Village, Yongji County, Shanxi Province from 221 to 207 BC (Qin Dynasty). After the establishment of New China, especially since the 1970s, under the strong promotion of reform and opening up, the bearing industry has entered a new period of high-quality and rapid development.

    Maintenance and upkeep of zinc alloy bearing seat
        

                    
        
    (1) Use of bearing seat cooling system. When used correctly, the cooling water for the bearing seat not only prolongs the service life of the bearing seat, but also improves production efficiency. The material of the bearing seat is generally made of specialized bearing seat steel through various treatments,

    Performance and installation of zinc alloy bearings
        

                    
        
    Zinc alloy bearings are a type of bearing unit that combines rolling bearings with bearing seats. Most outer spherical bearings are made of spherical outer diameter and installed together with imported bearing seats with spherical inner holes, with diverse structural forms, good universality and interchangeability. Zinc alloy bearings also have a certain degree of self-alignment in design, are easy to install, and have a dual structure sealing device that can work in harsh environments. The bearing seat is generally cast into shape. Commonly used seats include vertical seat (P), square seat (F), convex square seat (FS), convex circular seat (FC), diamond seat (FL), circular seat (C), slider seat (T), etc.

    Application and Classification of Joint Bearings
        

                    
        
    Joint bearing is a special type of sliding bearing with a special structure. Its structure is simpler than rolling bearings. It mainly consists of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, which can withstand large loads. Depending on its different type and structure, it can withstand radial loads, axial loads, or combined loads that exist both radially and axially.
