There are three rows of slewing bearings with rollers of different diameters as rolling elements. It is composed of three seat ring, three groups of rollers and spacers,

connecting bolts and dustproof ring. According to differnet load conditions, the upper row of rollers has the largest size, and the lateral rollers have the smallest size.

The upper and lower row of rolling elements bear axial force and verturning moment, while the lateral rolling elements bear radial force. It is a slewing bearing with

the largest bearing capacity. Mostly used in heavy construction machinery.

We also can use the steel cage or copper cage for the slewing bearing, and it used for fast speed.

For slewing bearing, it have three type of teet:

1. Outernal gear slewing bearing

2. Internal gear slewing bearing

3. Non-geared slewing bearing
