Gear teeth integrated into the outer or inner ring of a slewing bearing (also called a turntable bearing) provide a mechanical interface for power transmission. These teeth mesh with a pinion gear to convert rotational motion into controlled torque, allowing large structures to rotate smoothly under heavy loads while maintaining precise positioning. The gear teeth are typically cut directly into the bearing's hardened steel ring, creating a unified component that combines load-bearing capacity with power transmission functionality.

Gear teeth on slewing bearings operate on the fundamental principle of gear meshing. When a pinion gear engages with the teeth on the bearing ring, rotational force is transferred through the contact surfaces. The involute tooth profile ensures smooth engagement and disengagement with minimal backlash, while the bearing's raceways support axial, radial, and moment loads simultaneously. This integrated design eliminates the need for separate gear assemblies, reducing complexity and improving mechanical efficiency in applications requiring both rotation and load support.
