Machine tools are the carrier of advanced manufacturing technology and the basic production means of equipment industry. They are the basic equipment of equipment manufacturing industry, mainly serving industries such as automobiles, military industry, agricultural machinery, engineering machinery, power equipment, railway locomotives, ships, etc. The machine tool industry has strategic importance in both economy and technology, and its equipment design capability and manufacturing process level based on mechanical engineering technology and digital control technology make it at the forefront of the Fourth Industrial Revolution. With digitization 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 at its core, is more important than ever before.

The performance of the spindle unit is crucial for the quality of the mechanism parts and the normal operation time of the machine. The spindle unit plays a crucial role in machining operations, and its design range covers from belt driven spindles to motor integrated spindles, and is used in various machines ranging from high-speed milling to high load turning operations. The performance of machine tools is being pushed to its limits in order to maximize production. At the same time, machine operations are becoming increasingly complex, and the demand for higher speed and faster development has made the requirements for machine core components, especially spindle unit bearings, very high. Bearings have high operating accuracy, high-speed performance, and high system rigidity, making them an ideal choice for machine tool spindle units. At the same time, the design of this bearing can also reduce noise, vibration, and heat generation.

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.
