Features:
Slewing ring bearings have four-point contact ball bearings without 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 composite bearings. Series, four-point contact ball bearings have higher static load capacity, crossed cylindrical rollers have higher dynamic load capacity, and the pre-interference of crossed tapered roller bearings enables the bearing to have greater support rigidity and rotation accuracy.
The three-row cylindrical roller combined bearing leads to the height of the bearing due to the increase in load capacity, and various forces are borne by different raceways, so under the same force, the bearing diameter can be greatly reduced, so it has the characteristics of making the host more compact.
A slewing bearing with high load capacity. Slewing bearings are widely used in large-scale slewing devices of hoisting machinery, mining machinery, construction machinery, port machinery, marine machinery, and high-precision radar machinery and missile launchers. At the same time, it can also design, develop and produce various special structure slewing bearings according to the specific requirements of users.
