Must see: 2019 bearing damage comprehensive summary

Air compressor bearings and other consumption as air compressor machine, if long time don't teardown check the running status, so it is difficult to predict what will happen when some losses, and even damaged. Overall air compressor bearing case of damage may be due to the quality of the bearing itself can also be man-made, among these factors, does not rule out environmental interference. By 2019, I summarize the bearing spell damage of nine major case, hope to everyone in dealing with problems can have some help.

（ 1) Air compressor bearing the overall decline in the hardness of high temperature erosion serious or bearing box installation accuracy is not high, cause a damage of the bearing a serious dissection, serious deformation crack;

（ 2) Bearing don't get enough of lubricating oil in surface temperature high fever, and gradually becoming black unable to maintain normal work;

（ 3) Bearing in the installation gap is too small, result in different friction between the bearing strength increasing, formed a relatively obvious gap, and in the gaps with crack;

（ 4) The rivet due to long-term high speed bearing looseness happened, lead to play a supporting role bearing cage can't complete;

（ 5) Don't clean up with lubricating oil for a long time, form a lot of carbon, lead to bearing surface is very rough, thus forming a scratch;

（ 6) Artificial custody caused by poor condition leads to surface rust;

（ 7) The lubrication effect of lubricating oil is not beautiful, or mixed with foreign body in oil, in the process of transportation lead to wear and abrasion;

（ 8) Is responsible for the rolling bearing side accidentally electricity, leading to a current through the bearing;

（ 9) During the installation process, there are sharp hard object collided with the bearing surface, causing serious damage.

this is my summary of 2019 bearing concrete will encounter several major damage, hope to be useful.
