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 simplifying the equipment transmission system.
This bearing is widely used in scenarios with strict requirements on precision and power transmission, such as industrial robot rotary joints, CNC turntables, semiconductor manufacturing equipment, radar antenna bases, etc. When working, it not only ensures high-precision and high-stable slewing support through crossed rollers, but also completes power connection with the help of the outer ring gear, effectively meeting the precision operation requirements under high-frequency and heavy-load conditions. It is a key supporting component of high-precision mechanical systems.Centripetal Bearings,High-Quality Bearings,Industrial Bearings,Explore our premium centripetal and radial ball bearings.
