Precision slewing bearings are medium-to-large bearings that can withstand comprehensive loads. According to the rolling element structure, they are divided into four-point contact ball slewing bearings and cross roller slewing bearings. The bearings themselves have mounting holes, lubricating oil holes and sealing devices to meet the needs of different working conditions; they have the characteristics of compact structure, convenient guiding rotation, simple installation and easy maintenance.
According to the rolling element structure, our company's 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 gear ring, with internal gear, and with external gear. It 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.
