A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy things and transporting them to other places. The part that plays an important role is the slewing bearing.

Technical parameters required for slewing bearing selection as below:

1).Slewing bearing load (Includes axial load, radial load and tilting moment)

2). Percentage of each load and its occupation time

3). Speed or number of revolutions of the slewing bearing under each load

4).Circumferential force acting on the gear

5).Dimensions of the slewing bearing

6). Other operating conditions

The material, compressive property, abrasive resistance and hardness of balls will affect the load condition and service life of slewing bearing. XZWD slewing bearing Co., Ltd purchase balls from suppliers with high quality, and we will conduct test for the compressive property, abrasive resistance and hardness to ensure the quality of balls will meet the requirement.
