YRT460(YRTC460-XL)bearing as the key component of machine tool, its performance will directly affect the rotational accuracy, rotational speed, rigidity, temperature rise, noise and other parameters of machine tool, and then affect the quality of workpiece processing, such as the dimensional accuracy of parts, surface roughness and other indicators. Therefore, in order to maintain excellent machine tool processing ability, it is necessary to match high-performance bearings. 
among these bearings, precision angular contact ball bearings (see Figure 2) are the most widely used. We all know that the rolling element of angular contact ball bearings is a ball; because it is a point contact (different from the linear contact of roller bearings), it can provide higher rotational speed, less heat and higher rotational accuracy. In some ultra-high speed spindle applications, ceramic ball bearings (usually Si3N4 or Al2O3) are also used. 

 

With the deepening of industrial structure upgrading in China, the machine tool accessory bearing industry also shows the trend of industrial structure upgrading, that is, the proportion of CNC machine tool gradually increases, and the market of its accessory bearing YRT series bearing is objective. In the field of numerical control, the proportion of high-end numerical control machine tools (such as heavy machine tools, intelligent machine tools, etc.) is also on the rise.
