If iron filings, burrs, dust and other foreign matter into the bearing, will enable the bearing running noise and vibration, and even damage the raceway and rolling element. So before installing the bearing, must ensure that the mounting surface and installation environment clean.
Lubricating angular contact ball bearing operation and life of a very important influence. Grease base oil, thickener and additives. Grease performance is mainly determined by the base oil. Generally low-viscosity base oil suitable for low temperature, high-speed; high viscosity suitable for high temperature, high load.
The thickener related lubricating properties, water resistance of the thickener to determine the water resistance of the grease. In principle, a different brand of grease can not be mixed, and even if the same kind of thickener of the grease will adversely affect each other additive different. INA bearings coated with anti-rust oil, must be carefully cleaned with clean gasoline or kerosene, and then coated with a clean and high quality or high-speed high-temperature grease before installation. Totally enclosed bearings do not need to clean the fuel.
During use, to regular monitoring of INA bearings running external conditions, such as temperature, vibration and noise measurements, etc.. These regular checks will be early detection of potential problems and prevent unexpected machine to suspend the production plan to achieve improved plant productivity and efficiency.
In the course of the operation, the bearings have the correct re-lubrication, perfect performance. Angular contact ball bearings lubricated divided into the grease and oil lubrication. INA Bearing plays function, first select the appropriate conditions of use, the purpose of lubrication method. If there is only a lubrication, oil lubrication dominant. Greased expertise can simplify the bearing surrounding structures.
Select the correct amount of lubricant to take proper lubrication methods are crucial for the successful run of any bearing, angular contact ball bearing lubricant has three main functions: separation of the contact surface, reducing friction; heat; prevent corrosion. Vertical mill roll grinding applications, high temperature, shock, heavy, slow application environment makes is difficult to form INA bearings well lubricated conditions, severe dust environment and the impact is the deterioration of the lubrication conditions. The practical application results show that most of the grinding roller bearing damage are improper bearing lubrication results. Vertical mill roller bearings such poor application conditions, the lubrication system design choices, the circulating oil lubrication system is relatively effective one hand, the circulating oil can effectively take away most of the heat generated in the bearing work as well as external thermal radiation, on the other hand can also recycle oil away bearing that exist within the tiny impurities, purification of the bearing environment.
Sealed INA Bearing friction bearings working life have a great impact. It must prevent the lubricant from the bearing to leak out, and must prevent outside contaminants from entering the bearing. Small particles of abrasive work environment, a large number of small hard particles is easy access to the vertical roller mill roller bearings internal deterioration of the angular contact ball bearings work environment, reducing the lubrication effect, even in the raceway surface formation of the indentation, causing pitting and even raceway spalling, reducing the working life of the bearings. Therefore, the choice of sealing components for high reliability is essential to improve bearing life. In addition, the design of multi-sealed and in certain pressure inside and outside the design of the roller, you can effectively prevent outside contaminants from entering the internal bearings.
