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. Generally, precision turntable bearings have mounting holes, lubricating oil holes and sealing devices, which can meet the needs of different working conditions; on the other hand, precision turntable bearings themselves 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, turntables and indexing plates, machine tools, medical equipment, radars, wind power generation and tank turrets. 

Precision turntable bearings are divided into two series according to the rolling element structure: 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. They 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. 

Our company supports non-standard customized design and processing of various types of high-precision bearings with an inner diameter of 20mm to an outer diameter of 2300mm. We cooperate with many universities, machine tool companies, mechanical research institutes, and scientific research institutions all year round to carry out joint development of major equipment and assist customers with sample and mass production.
