Precision turntable bearings are medium-to-large bearings with special structures that can simultaneously withstand large axial loads, radial loads, overturning moments and other combined loads. They have the characteristics of compact structure, convenient guiding rotation, simple installation and easy maintenance. They are widely used in precision ship equipment, precision grinders, lathes, gear shaping machines, laser chucks, medical equipment, rotary tables and indexing plates, machine tools, radar wind power generation and tank turrets.

According to the rolling element structure, our company's precision turntable bearings are divided into two series: cross roller turntable bearings and four-point contact ball turntable bearings. According to the gear form, they can be divided into three types: without gear ring, with internal teeth, and with external teeth. It can be installed with seals, equipped with oil filling cups, and the clearance torque can be adjusted in a small range. The accuracy can reach P5/P4/P2 level to meet various working conditions.
