The life of mechanical bearings is not a fixed value, because it is affected by many factors, such as use conditions, workload, speed, lubrication, installation and maintenance. Therefore, it is impossible to give the exact life of mechanical bearings.


However, mechanical bearings will wear and age during use. When their performance drops to a certain extent, they need to be replaced. The following are some bases for evaluating whether bearings need to be replaced:


1. Bearing wear: Bearings will wear during use. When the wear reaches a certain extent, the performance of the bearing will decline, affecting the normal operation of the machine. Therefore, it is necessary to check the wear of the bearings regularly. If the wear is serious, the bearings need to be replaced.


2. Bearing lubrication: Good lubrication is an important guarantee for the normal operation of the bearing. If the bearing is poorly lubricated, it will cause the bearing to heat up, wear more, and even jam. Therefore, it is necessary to check the lubrication of the bearings regularly. If the lubrication is poor, it is necessary to lubricate or replace the bearings in time.


3. Bearing service life: The bearing service life is usually given by the manufacturer. When the bearing service life reaches or exceeds the service life specified by the manufacturer, it is recommended to replace the bearing.


In addition, the working environment of the machine will also affect the service life of the bearing. If the working environment of the machine is bad, such as high temperature, high humidity, dust, etc., it will affect the service life of the bearing. In this case, the replacement cycle of the bearing needs to be shortened.


In order to ensure the normal operation of mechanical equipment and extend its service life, it is necessary to regularly check and evaluate the status of the bearing and replace the bearing in time according to the actual situation. At the same time, correct installation and maintenance are also the key to extending the service life of the bearing.
