Swivel rod ends type and structure and load requirements

- Jul 19, 2019-

The swivel rod end is a spherical plain bearing, and the basic type is composed of inner and outer rings having a spherical sliding spherical contact surface. 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 a large load.

 

According to its different types and structures, the rotating rod ends can withstand radial loads, axial loads or combined loads of radial and axial forces. Since the outer surface of the inner ring is provided with a composite material, the bearing can be self-lubricated during operation. Generally used for low-speed oscillating motion, it can also be tilted in a certain range of angles. When the support shaft and the shaft housing hole are different, they can still work normally.

 

Spherical plain bearings and rod end joint bearings at the end of the rotating rod are available in a variety of designs and have different combinations of sliding contact surfaces. Each design and combination has unique properties that make it ideal for certain applications. Rod end joint bearings are mainly used for supporting parts where the concentricity is not high, the working surface pressure is large, and the slow swinging and turning motion are performed.

 

The rotating rod end belongs to the sliding bearing, which is lubricated with wear-resistant non-metallic materials, and also has oil passage lubrication type. Similar to GE20-ET, GE15-ET, etc. are joint bearings, the suffix is a specific type. The joint bearings are classified into GE, GEC, GEG, GEEW, GEK, GEH, etc., and the sizes and lubrication methods are different. It can be found in the classification of sliding bearings in the mechanical design manual.
