Outer Ring Toothed Crossed Roller Slewing Bearing

Crossed roller slewing bearings with toothed outer rings are mechanical core components that combine high-precision load-bearing and power transmission functions. They consist of an inner ring, an outer ring with an outer ring gear, cross-arranged cylindrical rollers and isolation blocks. They have a compact structure and high functional integration. Its core advantages are reflected in the dual design: first, the **crossed roller structure**, the cylindrical rollers are arranged crosswise at 90°, form line contact with the raceway, have a large contact area, can withstand axial force, radial force and overturning moment at the same time, have strong rigidity, outstanding anti-deformation ability, and rotation accuracy of micron level; second, the **outer ring ring gear design**, the precision ring gear machined on the outer ring can directly mesh with the driving device pinion, eliminating the need for intermediate transmission components, achieving efficient power transmission and si…
