A self-lubricating internally threaded rod end bearing refers to a joint bearing with a rod end or a device at the rod end. This type of bearing product is provided with a threaded extension rod, and the thread has a left-right rotation. The so-called self-lubricating internally threaded rod end bearing is assembled from self-lubricating radial joint bearing and rod end body.
Normally, in the self-lubricating internally threaded rod end bearing, the surface of the rod end body is plated, and the inner ring sphere is chrome plated. At present, it is mainly used in aviation, aerospace, engineering, metallurgy, mining, transportation, medicine, electric power, electronics, textile light industry and automatic water and rotary industrial machinery.
We know that self-lubricating internally threaded rod end bearings are inevitably accompanied by different phenomena such as sound, temperature and vibration during operation. Therefore, during the operation of the self-lubricating internal threaded rod end bearing, we can find the abnormal change of the bearing by listening, touching, observing and using the bearing fault diagnosis instrument, etc., and judging whether the rod end joint bearing can be in normal working condition according to the changed state.
