| Description |
Characteristics :
Slewing bearing is a special bearing, which can bear combined axial, radial loads and tipping moment. Generally, slewing bearing is equipped with installation holes, lubricant holes and sealing devices in order to meet various requirements of main equipments in various operation conditions. Besides, slewing bearing features compact in structure, convenient to guide and rotate, easy for installation and maintenance.
Application:
It is widely used rotary devices for rigging , transportation equipment, excavating equipment, port equipment, medical equipment and military equipment.
Types :
Slewing bearing is classified according to its structure into :
1. four-point contact ball slewing bearing
This type is generally composing of two housing washers, which is compact in structure and light with steel balls contacting with spherical cage at four points. It can bear axial, radial loads and tipping moment. It can be used for construction equipment including rotary transporter, welding machine, small/medium sized crane and excavators. Four-point contact ball slewing bearing honors quite high dynamic load capacity.
2. double-row angular contact ball slewing bearing
This type is equipped with three housing washers. Steel ball and separator can be directly led to top/bottom cage. Two steel balls in different bores are equipped to fit for different load condition. This kind of configuration is quite easy to operate, which can bear heavy axial load and tipping moment. It is quite big in axial/radial size and compact in structure, which makes it particularly suitable for those equipments like bridge crane and truck-mounted loading/unloading equipment.
3. crossed cylindrical roller slewing bearing
This type is generally composed of two housing washers, which features compact in structure, light, precise in manufacturing and small clearance during assembly. Thus it requires high-level precision for installation.
