1. Working temperature of joint bearing

The allowable working temperature of joint bearings is mainly determined by the paired materials between the sliding surfaces of bearings, especially the plastic sliding surface of self-lubricating joint bearings. Its bearing capacity will have a downward trend at high temperature. For example, when the sliding surface material of lubricating type joint bearing is paired with steel/steel, its allowable working temperature depends on the allowable working temperature of lubricant. But for all lubricating type and self-lubricating type joint bearings, can be used in the temperature range of -30℃ ~ +80℃, and maintain the correct bearing capacity.

2, joint bearing Angle

Joint bearing Angle adjustable than general heart of rolling bearing, very suitable for use in supporting parts of the concentricity requirement is not high, the joint Angle with the bearing structure of the bearing size, type, seal and bearing, in the form of general centripetal knuckle bearing range Angle is 3 ° ~ 15 °, angular contact bearing joints Angle range is 2 ° ~ 3 °, The Angle range of thrust joint bearing is 6° ~ 9°.

3, joint bearing coordination

In any case, the matching chosen by the joint bearing shall not cause uneven deformation of the ring. The selection of the matching nature and grade must be determined according to the working conditions such as bearing type, supporting form and load size.

4. Joint bearing loading and unloading

The loading and unloading of joint bearings should follow the following principles, that is, the force exerted by assembly and disassembly can not be directly transmitted through the spherical sliding surface. In addition, auxiliary loading and unloading tools, such as sleeves and disassembly devices, should be used to directly and evenly apply the loading and unloading force imposed by the outside world to the matching ring, or use auxiliary methods such as heating for loading and unloading without load.

5, joint bearing installation

When assembling joint bearing series, it is necessary to pay special attention to the location of the outer ring division surface. In order to avoid the load directly acting on the segmentation surface, it is necessary to maintain the segmentation surface at right angles to the consistent direction.

6, joint bearing lubrication

When the applied load and the speed produced by the swing movement are very small, the oil-fed joint bearing can be operated without lubrication. However, regular oil supplementation is generally necessary. During initial installation and operation, it is recommended that the lubrication cycle be moderately shortened.

No oil feed type joint bearings can be used without lubrication. However, if lithium soap-based grease is added before operation, the service life of joint bearings will be longer. If oil is injected into the space around the bearing, the joint bearing will be more effective in preventing the invasion of dust and foreign bodies.
