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; 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 broad.

Precision slewing bearings are divided into two series according to the structure of rolling elements: 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. 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 within the range of inner diameter 20mm to outer diameter 2300mm, and cooperates with many colleges and universities, mechanical machine tool companies, mechanical research institutes, and scientific research institutions throughout the year to carry out joint major equipment Develop and assist customers in sample and mass production.
