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. 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 combined radial and axial loads.

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 have a large non-concentricity, 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 sliding bearings and rod end joint bearings have a variety of designs, and there are different sliding contact surface combinations. Each design and combination has unique properties, making it particularly suitable for certain applications.

Similar to GE20-ET, GE15-ET, etc. are joint bearings, and the suffix is the specific type.

Joint bearings are divided into GE, GEC, GEG, GEEW, GEK, GEH and other types, with different sizes and lubrication methods, which can be found in the sliding bearing classification of the mechanical design manual.
