1. Slewing bearing originated in Germany 30 years ago, then was used widely all around the word.
 
2. Compared to the genernal bearings, slewing bearings not only rotate but also bear the axial force, radial force and resultant moment simultaneously.

Application:

1. Construction machineries, such as tower cranes, excavators, mobile cranes, other types of cranes, piling machines, and truck-mounted concrete pumps, etc. metallurgical and mining equipments, rock drilling machine, crushing machine
 
2. Offshore equipments, such as offshore platforms, all kinds of harbor and shipyard cranes, and deck cranes
 
3. Amusement rides: Rotating series, such as carousel and so on
 
4. Wind power generator: They help the rotor blades rotate easily in the wind and transform kinetic energy into electric power.
 
5. Military equipment such as naval vessels, radar antennas, and airborne vehicles
 
6. Medical equipment, such as ct scanners

7. In addition, the slewing bearing is available for robotics, solar energy, railway industary and so on

With the rapid development of economy, national key projects and urban infrastructure construction projects are being started one after another, leading to strong demand for various kinds of construction machineries. The slewing bearing products accompany such machines
