YRT rotary table bearing is a kind of slewing mechanism with outer ring rotation and inner ring support. It is mainly divided into three series: YRT type, YRTS type and YRTM type. These three series bearings have the same installation dimensions, different internal structures and similar performance. YRT series bearings are composed of three rows of rollers (as shown in the right figure). Two rows of axial rollers ensure stable axial load carrying capacity. One row of radial rollers ensures that the bearings can withstand radial forces and overturning moments, suitable for axial bearing. Slewing mechanism. YRT rotary table bearings are mainly used in CNC machine tool manufacturing.
As its core components, domestic YRT series bearings are still more dependent on imports. The accuracy parameters of domestic YRT rotary table bearings are also subject to international manufacturers. Since the beginning of the 21st century, especially with the launch of the national “high-end CNC machine tools and basic manufacturing equipment”, the development of the mechanical equipment industry has been greatly promoted, and the development process of “high-speed, precise, composite and intelligent” machine tools has been Further acceleration.
