Slewing Bearing Introduction
Release time:
2025-11-13
A slewing bearing is a large bearing capable of withstanding comprehensive loads, simultaneously bearing significant axial and radial loads and overturning moments. Slewing bearings generally feature mounting holes, internal or external gears, lubrication holes, and sealing devices, enabling a compact host machine design, easy guidance, and convenient maintenance.
Slewing bearings are available in four series: toothless, external gear, and internal gear four-point contact ball bearings; double-row angular contact ball bearings; crossed cylindrical roller bearings; crossed tapered roller bearings; and three-row cylindrical roller composite bearings. Four-point contact ball bearings offer high static load capacity, crossed cylindrical roller bearings offer high dynamic load capacity, and the preload of crossed tapered roller bearings provides high support rigidity and rotational accuracy.
Three-row cylindrical roller composite bearings, due to their increased load-bearing capacity, are positioned at a higher bearing height, with different forces borne by different raceways. Therefore, under the same load conditions, the bearing diameter can be significantly reduced, resulting in a more compact host machine. These are high-load-bearing slewing bearings.
Slewing bearings are widely used in large rotating devices of lifting machinery, mining machinery, construction machinery, port machinery, marine equipment, and high-precision radar machinery and missile launchers. We can also design, develop, and manufacture various special-structure slewing bearings according to specific customer requirements.
