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. In general, precision slewing bearings have installation holes, lubricating oil holes and sealing devices, which can meet the needs of different working conditions; on the other hand, precision slewing bearings have compact structure, convenient guidance and rotation, easy installation and easy maintenance 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, 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. Sealing, equipped with oil filling cup, small range adjustment of clearance torque, precision can reach P5/P4/P2 level, to meet the needs of 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 sample and mass production.
