External Gear Slewing Bearing

An external gear slewing bearing is a type of bearing used in various applications that require the transmission of rotational forces between two objects. It consists of two rings - an inner ring and an outer ring - with a set of ball or roller bearings sandwiched between them.

The outer ring of the slewing bearing has external teeth or gears that mesh with the teeth on the mating component, which could be a pinion gear, a gear rack or another gear. This arrangement allows the slewing bearing to transmit torque and rotational forces from one component to another.
