Rod end joint bearing is a joint bearing with a rod end or mounted on the rod end, it belongs to a class of joint bearing.
Rod-end joint bearings are mainly composed of an inner ring with an outer sphere and an outer ring with an inner sphere, which can bear large loads.

Characteristics:
 According to the different types and structures of rod end joint bearings, they can bear radial load, axial load or radial and axial combined load. Rod-end joint bearings are generally used for swing motion with low speed and can also be used for inclined motion within a certain range of angles. According to its different types and structures, it can bear radial load, axial load or radial and axial load.

Classification：
SI... Type E is GE... E-bearing and rod end assembly. Rod end with internal thread

The SA... Type E is GE... E-bearing and rod end assembly. Rod end with external thread

SI... Type ES is GE... ES bearing and rod end assembly. Rod end with internal thread

The SA... Type ES is GE... ES bearing and rod end assembly. Rod end with external thread

The SIB... S-shaped rod end with internal thread, the material is carbon structural steel

SAB... S-shaped rod end with external thread, the material is carbon structural steel

SQ... Type I is spherical rod end joint bearing, rod end is carbon structural steel
                                                                                                                                        
 

Maintenance mode of rod end joint bearing:

1、Regular maintenance; In order to ensure the normal operation of the main engine, according to the request of the main engine and the design theory and application experience of the bearing, a maintenance cycle is set for regular maintenance.

2、Fault maintenance: when the bearing is faulty, stop the machine for inspection and maintenance.

3、 Early warning maintenance: the application of advanced bearing fault diagnosis technology, stop real-time monitoring of the service state of bearings, put forward a warning before the occurrence of bearing problems, stop maintenance.

In the running process of bearings, there must be sound, temperature and vibration phenomena. Therefore, as for the maintenance and maintenance of bearings in operation, abnormal changes of bearings can be found by listening, touching, observing and using bearing fault diagnosis instruments, and whether rod end joint bearings can be in normal working state can be judged according to the changing state.
 

Application：
 Rod end joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, construction machinery, automation equipment, automotive shock absorbers, hydraulic machinery and other industries.
