What should we pay attention to when loading and unloading swivel joint bearing?

The swivel joint bearing can withstand large loads. Depending on their type and construction, it is possible to withstand radial loads, axial loads or combined loads of radial and axial forces. Since the outer surface of the inner ring is provided with a composite material, the swivel joint bearing can be self-lubricated during operation. Generally used for low-speed oscillating motion, and low-speed rotation, it can also be tilted within a certain angle range. When the support shaft and the shaft housing hole are different, the normal operation can still be performed. Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries

Swivel joint bearing
In any case, the joints selected by the swivel joint bearing shall not cause uneven deformation of the ferrule. The selection of the mating nature and grade must be determined according to the working conditions such as bearing type, support form and load size.
Loading and unloading of swivel joint bearing
The loading and unloading of swivel joint bearing should follow the principle that the force applied by assembly and disassembly cannot be transmitted directly through the spherical sliding surface. In addition, auxiliary loading and unloading tools, such as sleeves, detachers, etc., should be used to directly and uniformly apply the loading and unloading force applied by the outside to the ferrule to be fitted, or to perform load-free loading and unloading by an auxiliary method such as heating.

Installation of swivel joint bearing
When assembling the swivel joint bearing series, it is necessary to leave the position of the segment of the accidental circle. In order to avoid the load directly acting on the segmentation surface, the segmentation surface should be maintained at a right angle to the direction.
Lubrication of swivel joint bearing
The oil-filled joint bearing can be operated without lubrication when the speed generated by the application of the load and the oscillating motion is small. However, in general, it is necessary to replenish the oil regularly. It is recommended that the lubrication cycle be appropriately shortened during initial installation and operation.

The oil-free swivel joint bearing can be used without lubrication. However, if lithium soap based grease is added prior to operation, the life of the swivel joint bearing will be extended. If the grease is injected into the space around the bearing, the swivel joint bearing will be more effective in protecting against dust and foreign matter.
