The slewing bearing itself has the characteristics of compact structure, convenient guiding rotation, convenient installation and convenient maintenance.

Widely used in large-scale slewing devices, such as: lifting transport machinery, mining machines, construction machinery, port machinery, wind power generation, medical equipment, radar and missile launchers, etc.

In addition, the slewing bearing can withstand comprehensive loads such as relatively large axial loads, radial loads, and overturning moments. It is a large bearing with a special structure that integrates multiple functions such as support, rotation, transmission, and fixation. .

Slewing bearings occupy a very important position in our daily life and industrial production, and are widely used, which is why they can solve many problems in the field of construction machinery. Because the bearings have four-point contact ball bearings with no gear, external gear and internal gear, double-row angular contact ball bearings, crossed cylindrical roller bearings, crossed tapered roller bearings and three-row cylindrical roller combined bearings, etc. Various structural types, among which the four-point contact ball slewing bearing has high static load capacity; Crossed cylindrical roller bearings have high dynamic load capacity;

Crossed tapered roller bearings have high bearing rigidity and high rotation precision, so they are widely used in construction machinery.

The main function of the slewing bearing is to connect the upper and lower parts of the machine. During the operation of the machine, it bears the self-weight of the upper part and the load generated, so that the upper part rotates relative to the lower part.
