A Slewing Bearing is a type of rotational bearing or bearing assembly that can support axial, radial, and/or moment loads. It consists of two seat rings, which can rotate relative to each other, and typically include one or more rows of rolling elements that roll on a raceway. ACB Slewing Bearings can be used in a variety of applications, such as cranes, mining loaders and reclaimers, excavators, wind turbines, radars, packaging machinery, robotic arms and others.
1- Single-row ball bearing slewing rings with internal gear
2 – Single-row ball bearing slewing rings with external gear
3 – Double-row ball bearing slewing rings with internal gear
4 – Single-row cross-roller bearing slewing rings with external gear
5 – Three-row roller bearing slewing rings Axial-roller bearings with internal gear
6 – Double-row slewing rings Roller/ball combination bearings with external gear
They can be Four Point Contact Slewing Bearings (Single-row Ball slewing Bearings), Crossed roller Slewing Bearings, double-row ball or roller, three-row, combined (1 roller/1 ball), or guided raceways, depending on the application. They can also be designed as Toothless, Internal-Toothed, or External-Toothed Slewing Bearing.
