 The three-row roller slewing bearing consists of three races with its separated upper, lower and radial raceway, to certainly determine the loads of each row of rollers. It can take all kinds of loads simultaneously. It is the heaviest loading one of the four kinds of products. It has larger axial and radial dimension and stable structure. It is especially used for the large-diameter heavy-duty machinery such as wheel excavator, all terrain cranes, harbor cranes, ladle rotating and big-ton truck-mounted cranes etc.

we can also provide

Single-row ball slewing beaqring

Double-row contact ball slewing bearing,

Single-row crossed roller slewing bearing;

Three row roller slewing bearing;

and wheel bearings, thrust roller bearings, thrust ball bearings, large deep groove ball bearings, Cylindrical Roller Bearings, Tapered Roller Bearings, Split bearing, non-standard bearings. 

The slewing bearing has races. This kind of openly assembling is very handy. It can take large axial force, and overturning moment. When the radial force is larger than 0.1 times the axial force, its raceway must be designed specially. The slewing bearing features bigger axial and radial dimensions, and stable structure. It is especially used for tower cranes with mid-diameter or bigger, and truck-mounted cranes etc loading machinery.
