Resolution bearing the seal makes aluminum mill can not operate normally related factors

From aluminum ball bearing rolls in the assembly structure can be seen in its installed retaining lip plastic seal structure and after anti-scale, according to the actual theory, preferably in a sealed bearing in the case of the bearing lubrication is the ability to be safeguarded, but in the practical application of aluminum ball mill is there a big difference, relevant professional staff through a detailed analysis of this result is found to cause a certain reason:
1, the application of the bearing aluminum mill its poor working environment, the actual hot-strip mill at the operation, the bearings will be subjected to high temperatures, heavy and shock and many other conditions.
2, the bearing during operation of the high frequency removal work, finishing work for the bearing, since the amount of the roll and the bearing seat of conditions, each bearing to be repeated several times daily removal operation of the event to cleaning time period, thousands of times on the need for disassembly work, such an action would be nothing wrong with a certain impact on its tightness.
Aluminum mill in actual production, bearing the seal printed cable ties of the new pre-installed, which have varying degrees of bearing into the water, the latter in a sealed, water situation will be even more significant, is the bearing water has a very big influence. In the aluminum ball mill rotating at high speed, the bearing grease in the bearing and the inner pressure of the roll under the effect of the loss of cooling water, the number of mechanical impurities such as phosphorus oxide will be the roll cooling water into the bearing, the bearing roller promoter and are thus forming a raceway different levels of indentation. Ultimately the formation of pitting, and even fatigue spalling, if not promptly treated, can cause bearing accidents.
