Female rod end bearing installation, removal and maintenance

- May 11, 2018-

Installation and disassembly of female rod end bearings often require skilled operating skills. In practice, if the press is not available or cannot be used, rod end bearings can be installed using assembly bushings and hammers. The hammering force should be evenly transmitted to the entire circumference of the end face of the inner threaded rod end bearing ring, so the hammered end face of the fitting sleeve should be made into a spherical shape.


It should be noted that when female rod end bearing, the applied force is generally determined based on the size of the joint bearing and the amount of fit interference. For medium-size or large-size joint bearings with large interference, the hot-loading method is generally used. Before hot loading, put the rod end joint bearing or the separable joint bearing ferrule in the tank or dedicated heater and heat evenly to 80-100°C. Do not exceed 100°C.


When using hot mounting, remove the female end of the threaded rod end and clean it with a clean rag. Make sure that the oil stains and attachments on the bearing surface are cleaned and placed in front of the mating surface. In one operation, the joint bearing is pushed against the shaft shoulder. Always tighten during cooling, or use a small hammer to lightly press the joint bearing against the tight fitting sleeve. Remember, you can slightly rotate the bearing during installation to avoid stuck.


In practical applications, attention should also be paid to the maintenance and repair of female rod end bearing. In order to ensure that the host can work normally, a reasonable maintenance cycle should be established according to the request of the host and the design theory and use of the bearing to ensure regular maintenance. If abnormal problems are encountered during the application, the machine should be shut down for inspection and repair.


In order to ensure the service life of the internal thread rod end bearing, we also need to use advanced bearing operation diagnostic technology to monitor the status of its operation in real time and prevent it in time before the problem arises. In fact, the sound, temperature and vibration are inevitable during the operation of the internal thread rod end bearing. We can judge the working condition of the bearing through the status of these changes.
