Slewing rings, also be called slewing bearings, are large bearings capable of bearing axial force, radial force, and overturning moment simultaneously, and are often regarded as the "joints of machines."
Main characteristics of Slewing rings:
--Load capacity of Slewing rings: They can bear axial force, radial force, and overturning moment meanwhile. There are various structural form, with the three-row roller slewing ring having the largest load capacity.
--Compact and lightweight structure of Slewing rings: Some designs (such as four-point contact ball slewing bearings and crossed roller slewing bearings) are compact and lightweight, facilitating installation and maintenance.
--Precision and lifespan of Slewing rings: Adopt high-strength alloy materials and medium-frequency quenching technology, the raceway hardness can reach HRC55~62. Tolerances are controlled through digital technology, resulting in extremely high stability and a long service life.
--Performance and maintenance of Slewing rings: They feature low frictional torque and are relatively easy to maintain. 1. Main Application Areas of Slewing rings
The application range of Slewing rings is very wide, mainly covering the following areas:
--Construction Machinery: This is the earliest and most widespread application area of Slewing rings, including excavators, cranes, tower cranes, bucket wheel excavators, bulldozers, road rollers, rock drilling machinery, mobile crane equipment, etc.
--Wind Power Equipment: Used at the connection between the tower and nacelle of wind turbine generators to realize the yaw and pitch functions of the wind turbine.
--Marine and Port Equipment: Used in marine cranes, port cranes, molten steel transfer platforms, etc.
--Other Industrial Fields: Including rolling mills, tunnel boring machines, radar scanning equipment, medical equipment, industrial machinery, food filling machinery, etc.
