Do not check, identify or predict the operation of needle roller bearings, which is important for improving productivity and economy.

The main methods of needle roller bearing fault identification are as follows:

1) Through voice recognition

With sound, you need to have a rich experience. It is necessary to achieve sufficient training to identify needle roller bearing sounds and non-bearing sounds. For this reason, the work should be done by special personnel. The sound of the bearing can be clearly heard by the listener or listening bar.

2) Identify the working temperature of needle roller bearing

It is limited to those occasions which have not been changed in operation. To do this, continuous temperature recording must be performed. When there is a fault, not only does the temperature increase, there will be irregular changes.

3) through the lubricant status identification

The sampling analysis of lubricants can be judged by mixing foreign bodies or metal powders in needle roller bearings. This method is particularly effective for bearings or large bearings that cannot be close to observation.
