The slewing bearing(slewing ring bearing) is a large bearing that can withstand comprehensive loads and can withstand large axial and radial loads and overturning moments simultaneously. The shape types of most slewing bearings are as follows：
The slewing bearing is usually composed of a worm, slewing bearing, housing, motor, and other components. Since the core part adopts slewing bearing, it can bear axial force, radial force, and tipping moment at the same time. There are many forms, but the structure is basically the same.
The slewing bearing itself has a compact structure, is easy to use, and is easy to install and maintain. It has been widely used in marine equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery, and other industries.
C45, 50Mn (carbon structural steel), 42CrMo (alloy structural steel). Usually, 50Mn and 42CrMo are used.
Roller: it is made of GCr15 or GCr15SiMn steel.
Sealing: The material of the sealing ring is generally made of oil-resistant nitrile rubber (NRB). For special requirements, hydrogenated nitrile rubber (HNRB) and fluorine rubber (FKM) can be selected.
Generally, the structure of the slewing bearing that we can provide is as follows:
*Special-shaped or special products can be customized according to the drawings required by customers.
The main application of slewing bearings:
Slewing bearing for excavator:
We can choose the slewing bearing according to the machine model. Most of our slewing bearings are in stock and can be delivered quickly.
Slewing bearing for crane:
Due to the lightweight of the crane, the slewing bearing is an important component. Our slewing bearings are widely used in various types of cranes, such as tower cranes, deck cranes, mobile cranes, railway cranes, and so on.
Slewing bearings for marine ships:
Since the slewing bearing is used in special conditions at sea, we have a specially designed sealing system and surface protection. Our specific design mainly meets manufacturers’ ship and port cranes, hoists, davits and tire cranes, and propellers.
DK-bearing provides high quality all kinds of slewing bearings. Looking forward to your inquiry.
