Inner Ring Toothed Crossed Roller Slewing Bearing

Crossed roller slewing bearings with inner ring teeth are mechanical core components that combine high-precision load-bearing and direct power transmission functions. They consist of an inner ring with an inner ring gear, an outer ring, a cross-arranged cylindrical roller and an isolation block. It has a compact structure and high functional integration. It is suitable for scenarios that have strict requirements for both accuracy and power transmission. Its core advantages come from two major designs: First, the **crossed roller structure**. The cylindrical rollers are arranged in a 90° cross arrangement and form line contact with the raceway. The contact area is much larger than that of ball bearings. It can withstand axial force, radial force and overturning moment at the same time, and has strong rigidity and vibration resistance. The dynamic deformation ability is outstanding, and the rotation accuracy can reach the micron level; secondly, the inner ring ring gear design**, the pre…
