Without dismantling inspections, it is important to identify or predict the failure of a bearing during operation, and to increase productivity and economy.
The main identification methods are as follows:Recognize by sound
Identifying sounds requires extensive experience. Must be adequately trained to recognize bearing and non-bearing sounds. To do this, we should try our best to do this work. The sound of the bearing can be clearly heard with the earphone or the sound bar attached to the housing.
Recognition by operating temperature
This method is a comparative method of identification and is limited to applications where the operating conditions do not change. For this reason, continuous recording of temperature must be performed. When a fault occurs, not only the temperature rises, but also irregular changes occur.
Recognized by the state of the lubricant
Lubricant samples were analyzed and judged by whether the degree of contamination was mixed with foreign matter or metal powder. This method is particularly effective for bearings that cannot be observed close to or large bearings.
