Slewing bearings are large diameter rolling bearings that can be used in a combination of axial, radial and torque loads is applied when rotating or oscillating.
The slewing support consists of 2 or 3 rings, in between the rings Spherical or cylindrical rolling elements are arranged with suitable gaskets or cages.
These rings contain mounting and operating holes, as well Integral spur gear, spiral gear or worm gear drive. Lip seals prevent contaminants from entering the raceway.

Slewing bearing is a key component used in engineering machinery, construction machinery, metallurgical machinery, electric machine and other equipment. It has the characteristics of large weight, flexible rotation, convenient installation and so on. 1, construction machinery: such as excavators, cranes, etc., slewing support as a rotating part of the excavator, bearing the rotation and load of the whole machine, to ensure the normal operation of the whole machine. 2, metallurgical machinery: such as continuous casting machine, steelmaking machine, etc. The rotation of the device ensures that the continuous casting machine can be carried out. 3, motor: such as generator sets, wind turbines, etc., rotating bearings as a rotating mechanism of the generator set, supporting the rotor, the mechanical energy into electrical energy. In the specific selection and calculation process, it is necessary to consider the brand, quality, manufacturing process and other factors of the slewing bearing, as well as the specific requirements of the user, environmental conditions and other factors, therefore, the choice of the right slewing bearing needs to consider many factors
