Fault identification methods for bearings


It is very important to identify or predict whether there are faults in the running bearings without disassembly inspection, in order to improve productivity and economy.

The main identification methods are as follows:

1. Recognition through sound

Recognition through sound requires extensive experience. Must undergo sufficient training to recognize bearing and non bearing sounds. To this end, it is advisable to have dedicated personnel carry out this work as much as possible. The sound of the bearing can be clearly heard by sticking a listening device or stick to the casing.

2. Identification by operating temperature

This method belongs to the comparative recognition method and is only applicable in situations where the operating state does not change significantly. For this reason, continuous temperature recording is necessary. When a malfunction occurs, the temperature not only increases but also undergoes irregular changes. It is advisable to use this method in conjunction with voice recognition methods.

3. Identification by the state of the lubricant

Sample and analyze lubricants to determine their degree of contamination, whether foreign objects or metal powder have been mixed. This method is particularly effective for bearings or large bearings that cannot be observed closely.
