Precision slewing bearings are medium and large bearings with a special structure that can withstand comprehensive loads such as large axial loads, radial loads, and overturning moments at the same time. It has the characteristics of compact structure, convenient guidance and rotation, easy installation and easy maintenance, etc. It is widely used in precision ship equipment, precision grinding machines, lathes, gear shaping machines, laser chucks, medical equipment, rotary tables and indexing plates, machine tools ,radar wind power generation and tank tower guns and other devices.According to the structure of rolling elements, our precision slewing bearings are divided into two series: cross roller slewing bearings and four-point contact ball slewing bearings. According to the gear form, they can be divided into three types: without ring gear, with internal teeth and with external teeth. . It can be installed with seals, equipped with oil filling cups, and can adjust the clearance torque in a small range, and the precision can reach P5/P4/P2 levels to meet the needs of various working conditions.
