As an important part of the machine tool, the turntable has always been the focus of machine tool design. As a key component for carrying workpieces, the rotary accuracy, rigidity and combined bearing capacity of the turntable directly affect the processing performance of the machine tool, and the selection of the bearing plays a direct and decisive role. The traditional solution for the light bearing of the turntable generally uses two or more sets of radial and thrust bearing combinations, the purpose of which is to enable the turntable to bear axial loads, radial loads and overturning moments at the same time. Although this solution is mature, but There are also many disadvantages such as complex design of turntable structure and inconvenient installation and maintenance of bearings.

HRTG standard series

Thrust-centripetal combined structure, can bear bidirectional axial load, radial load and overturning moment at the same time. Mounting holes are evenly distributed on the bearing, and the bearing can be directly fixed by bolts; the bearing has been preloaded before leaving the factory, and there is no need to adjust the clearance for installation ;This series is suitable for occasions with low speed, short operation period and high rigidity and precision requirements, such as rotary table, dividing head, etc.

HRTGS high speed series

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

HKLDF-B standard series

Thrust angular contact ball series can withstand combined loads, have extremely high speed and low friction moment, and at the same time can ensure high rotation accuracy. It is very suitable for applications with such requirements, such as high-speed rotary tables, milling, grinding, grinding heads, precision measurement, testing equipment, etc.

HRTGM Integrated Angle Measurement System Series

The angle measurement system is integrated on the basis of the HRTG series, which can realize the precise measurement of the angle, and the highest accuracy can reach ±1 arc second, which is very suitable for applications that have high requirements for angle positioning accuracy.
