As a kind of bearing field, slewing bearing is more and more widely used in modern society. It is called "the joint of the machine". Its main application is widely used in: truck cranes, railway cranes, Port cranes, marine cranes, metallurgical cranes, container cranes, excavators, filling machines, and CT standing wave therapy instruments, navigation instruments, radar antenna bases, missile launchers, tanks, robots and revolving restaurants, etc.
What is the importance of lubricating the raceway of a slewing bearing?
Where can we find slewing bearings in life?
What is the control method for the slewing ring to produce scar sound?
The raceway must be regularly lubricated with grease according to the working environment. The raceway should be filled with lubricating grease after 50 working hours for the first time, and then every 300 working hours after that. The slewing bearing must be filled with grease before and after being placed for a long time.
If a steam jet cleaner or stationary water jet is used to clean the crane, care must be taken to ensure that water does not seep into the slewing bearing connection, and the slewing bearing connection must then be lubricated. In special working environments, such as tropical areas, high humidity, dust, large temperature changes and continuous work, the lubrication cycle should be shortened.
Filling grease should be carried out under the condition of slow rotation of the slewing bearing. When the grease overflows from the seal, it means that the filling is completed, and the overflowing grease will form a film to act as a seal.

2. Airport equipment: airport tanker;
3. Military equipment: radar, tanks, etc.;
4. Robots: palletizing robots, welding robots, manipulators;
5. Medical equipment: Gamma Knife;
6. Environmental protection equipment: mud scraper;
7. Parking equipment: tower garage;
8. Drilling platform equipment, kitchen equipment, CNC equipment (wire cutting machine, quenching machine tool), brick machine.
If the rolling surface of the slewing bearing is cracked, indented or corroded, periodic vibration and noise like riveting rivets will occur. The period may be fixed but most of them have a certain corresponding relationship with the rotation speed, and the scars will be continuous on the channel. Occurs, scars appear and disappear on the steel ball, and this noise varies with installation and lubrication conditions.
The control method of this kind of noise: do not knock the bearing during installation, prevent the bearing from tilting when assembling the bearing and the shaft and then put it into the bearing seat; prevent the bearing from rusting during stocking and prevent shock and vibration during transportation; use high-viscosity grease.
