Spherical plain bearings are a special type of bearings that are primarily used to support, position and limit moving elements in mechanical equipment. Its main functions are:

1. Support the weight of equipment: joint bearings help support the weight of mechanical equipment, thereby reducing the frictional resistance of mechanical equipment;

2. Provide positioning function: joint bearings can provide positioning function to ensure that the moving parts of the equipment remain stable during installation and use;3. Anti-vibration and noise reduction: joint bearings can resist vibration and reduce the noise generated when mechanical equipment is running;

4. Reduce equipment loss: joint bearings can provide good support, so that its moving elements can absorb shocks efficiently and reduce equipment loss;

5. Extend the service life of the equipment: the good support and positioning function of the joint bearing can greatly extend the service life of the mechanical equipment
