Application and Performance Characteristics of Rod End Joint Bearing

- May 14, 2018-

As a kind of sliding bearing, the structural design of the rod end joint bearing is generally quite special. In comparison, the structure of the rod end joint bearing is simpler than the structure of the rolling bearing, mainly consisting of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, which can withstand a large load. At the same time, in different workplaces, suitable types can be selected according to actual requirements.


In practical applications, rod-end joint bearings are mostly used for slow-moving swing motions, that is, angular motions. Because the sliding surface has a spherical shape, it is also possible to perform tilting movement within a certain range of angles, that is, aligning movements. When the misalignment between the support shaft and the bore of the shaft shell is large, it can still work normally. Due to the composite material embedded on the outer sphere of the inner ring, this type of bearing can be self-lubricating during operation.


For the user, the rod end bearing has good stability. Even when the bearing shaft and shaft housing hole are different in heart, the normal operation can still be maintained. At present, the joint bearing has been widely used in engineering hydraulic cylinders, forging presses, construction machinery, automation equipment, automotive shock absorbers and hydraulic machinery and other industries. Because the spherical sliding contact area of the spherical plain bearing is large and the inclination angle is large, special processing methods such as surface phosphating, galvanizing, and chrome plating are often used when processing.


In this way, the use performance of the product is greatly improved, so the rod end joint bearing also has a strong load capacity and has excellent impact resistance. Moreover, in practical applications, it also exerts excellent properties such as good corrosion resistance, wear resistance, self-aligning, and good lubrication. Therefore, it has been loved by many users.


In addition, the structure of the rod end joint bearing itself is relatively simple, easy to use, and has a long service life. Moreover, with the development of the market, the number and type of rod end joint bearings are becoming more and more abundant, and users can choose according to their needs.
