Spherical Bearings Selection
Apr 16, 2018

As the market requirements for various mechanical devices and instruments using rolling bearings become increasingly stringent, the conditions and performance required for spherical bearings are increasingly diversified. In order to select suitable spherical bearings from a large number of structures and sizes, it is necessary to study from various angles.

 

In the selection of spherical bearings, it is generally considered as the spherical bearing arrangement, installation, removal of the degree of difficulty, the space allowed by the spherical bearing outside the bearing, the size and marketability of spherical bearings, etc., to determine the approximate bearing structure. On the basis of this, the bearing size is determined while comparing the design life of various machines using bearings and various different durability limits of the bearings.

 

The selection of spherical bearings, in addition to considering the fatigue life of the bearing, the grease bearing life, wear, noise, etc., occurring due to grease aging also need to be fully studied. Furthermore, depending on the application, it is necessary to integrate spherical bearing accuracy, clearance, cage structure, grease, and other requirements.

 

In fact, the choice of spherical bearings does not have a certain order and rules. The priority should be given to the conditions and performance required for bearings. In the use of spherical bearings, good lubrication is very important for it, so it is a good choice for the lubricant it uses.

 

In general, the lubricant between the two fingers rubs, or in a thin layer of lubricant, and then seal inspection. In order to ensure the purity of the spherical bearing lubricating oil, it must be filtered and replaced regularly before use so that the spherical bearing can maintain good lubrication.
