Function:

The crane slewing bearing is a vital part in the crane, and its main functions are as follows:
1. Connection and support
The slewing bearing connects the slewing part of the crane (e.g. the lifting arm, the operator's cab, etc.) with the non-slewing part (e.g. the chassis) to provide stable support for the slewing part. It can bear the weight from the lifting arm and the load to ensure that the crane remains balanced during operation.
2. Achieving smooth rotation
The slewing support enables the upper structure of the crane to rotate smoothly through 360 degrees relative to the lower structure. This swivelling function greatly improves the operational flexibility and efficiency of the crane.
3. Supporting combined loads
The slewing bearings are able to withstand large axial and radial loads and overturning moments at the same time. This high load carrying capacity ensures stable operation of the crane under high intensity and high frequency working conditions.
4. Transmission of power and torque
The slewing bearing not only supports the rotating parts, but also transmits power and torque from the drive unit to the slewing section. This function enables the crane to precisely control the speed and direction of rotation.
5. Reducing friction and wear
The design of the slewing ring reduces energy loss and component wear by converting sliding friction into rolling friction through the design of the rolling elements. This not only improves the operating efficiency of the crane, but also extends the service life of the equipment.
6. Adaptable to various working conditions
The slewing bearing has good abrasion and corrosion resistance, and can be used for a long time in harsh working environments. Its sealing design can also prevent dust and impurities from entering, further improving reliability.
