Rod end joint bearing

Rod end joint bearings are joint bearings with rod ends or mounted on rod ends, which belong to a class of joint bearings.
Joint bearings are spherical sliding bearings, and the basic type is composed of inner and outer rings with spherical sliding spherical contact surfaces. The joint bearing is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, which can withstand larger loads. According to its different types and structures, it can bear radial load, axial load or a combined load of both radial and axial. Because the outer spherical surface of the inner ring is inlaid with composite materials, the bearing can produce self-lubrication during operation. It is generally used for low-speed swing motions, and can also be used for tilting motions within a certain angle range. When the support shaft and the shaft housing hole are not concentrically large, it can still work normally. Self-lubricating joint support is used in water conservancy, professional machinery and other industries. Because the spherical sliding contact area of ​​the spherical plain bearing is large, the inclination angle is large, and also because most of the spherical plain bearing adopts special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, inserting, spraying, etc. Therefore, it has a large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self-aligning, good lubrication or self-lubricating without lubricating dirt pollution, and it can work normally even if the installation is misplaced. Therefore, joint bearings are widely used in low-speed swing motion, tilt motion and rotational motion. Spherical plain bearings and rod end joint bearings have a variety of designs, and there are different combinations of sliding contact surfaces. Each design and combination has unique properties, making it particularly suitable for certain applications. Radial spherical plain bearings requiring maintenance
Maintenance-free spherical plain bearings
Angular contact spherical plain bearings
Spherical sliding thrust bearing
Rod end joint bearing
To select a certain bearing type, to determine the required bearing size, the main factors must be considered
It is the load, the load capacity of the bearing and the expected service life. This is also true when selecting rod ends.
