As an important component of machine tools, turntables have always been the focus of machine tool design. As a key component for carrying workpieces, the turntable's rotation accuracy, rigidity and composite load-bearing capacity directly affect the processing performance of machine tools, among which the selection of bearings plays a direct and decisive role. The traditional solution for turntable light bearings generally uses two or more groups of radial and thrust bearings in combination, in order to enable the turntable to simultaneously withstand axial loads, radial loads and overturning moments. Although this solution is mature, it also has many disadvantages such as complex turntable structure design and inconvenient bearing installation and maintenance.

The thrust-centripetal combined structure can simultaneously bear bidirectional axial loads, radial loads and overturning moments. The bearings are evenly distributed with mounting holes, and the bearings can be directly fixed with bolts. The bearings are preloaded when leaving the factory, and no clearance adjustment is required for installation. This series is suitable for applications with low speed, short operating cycle, and high rigidity and precision requirements, such as rotary tables, dividing heads, etc.

The HRTGS series rotary table bearings have the same external structural dimensions as the HRTG series rotary table bearings, but their special internal structural design enables them to have a higher limit speed, and the friction force is low and uniform in the entire speed range. Therefore, it is suitable for applications similar to the HRTG series but requiring lower friction and higher speed, such as bearing applications for direct drive shafts, and is especially suitable for the selection of bearings in CNC rotary table structures.

The thrust angular contact ball series can withstand combined loads, has extremely high speeds and extremely low friction torques, and can also ensure high rotation accuracy. It is very suitable for applications with such requirements, such as high-speed rotary tables, milling, grinding, grinding heads, and precision measurement and testing equipment, etc.

The HRTG series integrates an angle measurement system to achieve precise angle measurement with a maximum accuracy of ±1 arc second, making it very suitable for applications with high requirements for angle positioning accuracy.
