1. troubleshooting: If the bearing fails, check out and repair.
2. periodic maintenance: in order to ensure normal host, based on the requirements of the host and bearing design theory and experience, set a maintenance cycle, regular maintenance.
3. early warning service: bearing fault diagnosis using advanced technology for rolling mill bearings used for real-time monitoring, forecast to be made before the bearing fails, for repairs.
NSK bearings in operation process, there must be sound, temperature and vibration occurs. Therefore, the bearing in operation for maintenance, you can listen to, touch, view, and use method of bearing fault diagnosis instrument found bearing abnormal changes, depending on the status change to determine whether rolling mill bearings are in good working condition.
Bearing load capacity than the same volume of rolling mill bearing is much smaller, and therefore its rolling bearing radial dimensions. So, to bear large loads of compact small radial dimensions, structural requirements and requirements of crankshaft bearings, NSK bearings.
Bearings are particularly sensitive to foreign objects such as scrap metal, once mixed with foreign bodies, will produce intermittent vibration and noise of large, easily lead to damage. So the life of rolling bearings have some limits. In short, similar bearings NSK bearing a shorter life expectancy.
High temperatures are often said to be in unusual circumstances. High temperatures may also be harmful to the bearing lubricant. Sometimes overheated bearing could be attributed to the bearing lubricant. Bearing temperature long-term continuous transfers of more than 125 ° c reducing rolling mill bearing life. Cause of the high temperature bearings including: inadequate or excessive lubrication lubrication, lubricant. Contains impurities, excessive load, rings of bearing damage, inadequate clearance, and oil have high friction and so on.
