Performance of the Spherical Plain Shaft Bearings

Because the structure and working mechanism of the spherical plain shaft bearing are completely different from the rolling bearing, the rod end joint bearing has its own technical characteristics and maintenance requirements.

 

 

Operating Temperature of the spherical plain shaft bearing

The operating temperature of the spherical plain shaft bearing is mainly determined by the materials between the sliding surfaces, especially the plastic material used in the sliding surface of the self-lubricated bearing. What is more, the capacity of load of the spherical plain bearing will decrease at high temperatures. For example, when the material of the sliding surface of the self-lubricated bearing is steel, its operating temperature will depend on the operating temperature of the lubricant. However, for all types of self-lubricated bearings, they can be used in the temperature with a range of -30 °C to 80 °C. Also, in reasonable temperature, the rod end joint bearing can maintain the correct capacity of load.

Inclination of the spherical plain shaft bearing

The angle of inclination of the knuckle bearing is much larger than that of a rolling bearing. Furthermore, it is suitable for using in support parts with low requirements of concentricity. The angle of inclination of the bearing will vary with the size and type of the structure of the spherical plain bearing. Also, the angle depends on the sealing device as well. The range of inclination of the rod end joint bearings is from 3 ° to 15 °.

 

 

Cooperate of the spherical plain shaft bearing

In any case, any deformation which is uneven will not be caused by the rod ends selected for the rod end joint bearings, and the choice of the rod ends must be determined according to the working conditions such as types of bearing, supporting.

 

 

Installation of the spherical plain shaft bearing

The installation and dismantling of joint bearings should follow the principle that the force applied during assembling and disassembling cannot be directly transmitted through the sliding surface of the rod end joint bearing. In addition, tools such as sleeves should be used to distribute the force to the knuckle bearing directly and evenly.

 

 

Installation of the spherical plain shaft bearing

When assembling the knuckle bearings, it is necessary to care about the keep the position of the surface of the outer ring. It is necessary to maintain the surface at right angles in order to avoid the load is directly placed on the surface.

Lubricating of the spherical plain shaft bearing

When the load and the speed of the swing motion are small, some types of the rod end joint bearings which are lubricated by oil can be operated without lubrication. However, in general, grease must be replenished regularly. During the initial installation and operation of the rod end joint bearing, it is recommended that the period of lubrication should be moderately shortened.

 

Oil-free bearings can be used without lubrication. However, if grease is added before the operation, the service life of the bearings will be extended longer. If grease is injected into the space around the bearing, the bearing will be more effective in preventing the intrusion of dust and so on.
