Slewing Bearing

Double row angular contact ball slewing bearings

Main structural characteristics: two rows of steel balls of different diameters are placed to bear the axial force and upsetting moment. The most prominent feature is flexible rotation, but its bearing capacity is lower than that of the triple-row cylindr

Three row cylindrical roller slewing bearing

Main structure characteristics: two rows of cylindrical rollers are laid horizontally around the circumference mainly to bear high axial load and upsetting moment; and one row of cylindrical rollers are laid vertically mainly for the upsetting
