The digitalization of the machine tool industry leads the industry process, and equipment standards based on geometric accuracy, motion accuracy, transmission accuracy, and dynamic accuracy have become important indicators for evaluating machine tool accuracy. As the core mother machine of industrial production, its performance has a profound impact on the productivity and competitiveness of enterprises. Machine tools are the carrier of advanced manufacturing technology and the basic production means of equipment industry. They are the fundamental equipment of equipment manufacturing industry. With digitalization becoming the core driving force, exciting opportunities for further automation have emerged. The key goal of optimizing overall equipment efficiency, with reliable performance and sustainability as the core, is more important than ever.

Various types, series, designs, variations, and sizes of ultra precision bearings are combined with optimal design to improve equipment performance, machine running time, speed, and accuracy. To meet the environmental requirements in recent years, a grease supply system was first introduced for the special bearings of machine tool spindles, and in the high-speed field that could only be achieved by lubricating oil in the past, a method of lubricating with grease was also realized. Various types, series, designs, variations, and sizes of ultra precision bearings are combined with optimal design to improve equipment performance, machine running time, speed, and accuracy.
