Product Description

Slewing bearings comprise an inner ring and an outer ring, one of which usually incorporates a gear. Together with attachment holes in both rings, they enable an optimized power transmission with a simple and quick connection between adjacent machine components. The bearing raceways, in conjunction with the rolling elements and cages or spacers, are designed to accommodate loads acting singly or in combination, and in any direction.

According to the stress conditions, the upper and lower rows of steel balls with different diameters are arranged. This open type assembly is very convenient. The bearing angle of the upper and lower circular arc raceways is 90 °, which can withstand large axial force and tipping moment.

Single-ROW Four Point Contact Ball Slewing Ring (Series Q) External Gear Features and Benefits

The single row four point contact ball slewing bearing is composed of two seat rings, which is compact in structure and light in weight. The steel ball is in four point contact with the circular arc raceway, and can bear the axial force, radial force and tipping moment at the same time. Rotary conveyors, welding operators, small and medium-sized cranes, excavators and other engineering machinery can be selected.

Slewing ring bearings can also be divided into three different types

Double-ROW Slewing Ring Gear

Slewing ring bearings with no gear

Slewing ring bearings with external gear

Slewing ring bearings with internal gear
