The service life of the bearing of ball mill directly affects the interests of customers

 There are many ways of bearing failure commonly used in large mechanical equipment. Most of the failures are method fatigue life, wear life, lubrication life and fretting life. These all need to be calculated and evaluated accordingly. Today, a large steel casting will introduce to you the different failure modes of bearings:

 
1. Fatigue life. If the lubrication conditions are normal, the bearing is often aging due to fatigue. Its service life can be obtained according to the sample query and can be calculated according to the formula.

2. Wear life, mechanical equipment is used with bearing housings. Under long-term use, before it reaches complete fatigue, it will often cause its accuracy to be unsustainable due to wear. In fact, many bearing housings are caused by excessive surface wear. expired.
 
3. Lubrication life. For grease bearings with double sided seals, there is no need to add them after grease filling. At this time, you need to see its service life.
 
4. Abrasion life. Bearings used for large-scale mechanical equipment will suffer fretting erosion damage due to shock load when they are not in operation. This is also the main reason for the failure of the bearing seat of the coal mill.
