Precision slew bearings are medium and large bearings with a special structure that can simultaneously bear large axial loads, radial loads and overturning moments and other comprehensive loads. Generally speaking, precision slewing bearings themselves have mounting holes, lubricating oil holes and sealing devices, which can meet the needs of different working conditions; on the other hand, precision slewing bearings themselves have compact structure, convenient rotation guidance, easy installation and easy maintenance. It is widely used in precision ship equipment, precision grinders, lathes, gear shaping machines, laser chucks, medical equipment, rotary tables and indexing plates, machine tools, medical equipment, radar, wind power generation and tank turrets, etc. Very extensive.

According to the rolling element structure, precision slew bearings are divided into two series: crossed roller slew bearings and four-point contact ball slew bearings. According to the gear form, they can be divided into three types: without ring gear, with internal teeth, and with external teeth. They can be installed. Sealed, equipped with an oil filling cup, the clearance torque can be adjusted in a small range, and the accuracy can reach P5/P4/P2 levels to adapt to various working conditions.

Our company supports non-standard customized design and processing of various types of high-precision bearings ranging from an inner diameter of 20mm to an outer diameter of 2300mm. We cooperate with many universities, mechanical machine tool companies, mechanical research institutes, and scientific research institutions all the year round to jointly conduct major equipment Development, assisting customers with samples and mass production
