A brief discussion on the failure phenomenon of powder bearing oil bearing

When the product has been put into use for a period of time, there will be some problems. In fact, the quality of this product has an inseparable relationship, but not all of them are caused by quality problems, may also be due to improper operation or operation mode caused by different. We summarize some problems arising from the use of PM bearings.

The most common corrosion problem of P/M oil bearing is the pad surface corrosion. Spectral analysis shows that the concentration of non-ferrous metal elements is higher, and there are more non-ferrous metal costs in the element spectrum, or the water or acid value in lubricating oil exceeding the standard will cause this corrosion problem.

The surface of shaft diameters of P/M oil bearing will be pulled up and corroded to a certain extent, which is also due to the existence of all cutting abrasive grains in the bearing, the main component of which is non-ferrous metal. If a certain fretting wear is found on the back of the tile, it may be that the iron concentration is abnormal, and there are more sub-micron wear particles with iron composition.

Through analysis and summary, we can obtain the fault reasons according to the problems of powder metallurgy oil bearing, and formulate a practical and effective correction program to ensure the effective service life of products.
