Slewing Bearings

Slewing Bearings

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 race-ways, in conjunction with the rolling elements and cages or spacers, are designed to accommodate loads acting singly or in combination, and in any direction.

Commonly used slewing bearing devices can be divided into the following four structures according to the shape and arrangement of rolling elements:


Single-row four-point contact ball slewing bearing consisting of two seat rings, compact  structure, lightweight, steel ball and arc race-way four-point contact, can simultaneously withstand axial force, radial force and tilting moment.

Composed of two seat rings, Single-row crossed roller slewing bearing has a compact structure, lightweight, small assembly clear-ance, and high requirements for installation accuracy.

Double-row ball slewing bearings consist of two one-piece rings and two independent rows of balls. The ball set can be a full comple- ment design or separated by a window-type steel cage or polyamide spacers.

Triple row roller slewing bearings are com- bined cylindrical roller radial/thrust bearings. They consist of one one-piece and one two-piece ring as well as two roller sets to accommodate axial loads, and one roller set to accommodate radial loads.
