INA angular contact ball bearing performance and test methods

Angular contact ball bearing is one of the important parts on construction machinery, poor installation will affect its use effect, even result in engineering machinery and equipment failure. After bearing installed, if not done carefully alignment, alignment could lead to INA bearings to suffer another load, friction, and vibration. The use of these may accelerate fatigue and reduce the bearing life, and it might damage the other machine parts service life. In addition, the increase of vibration and friction could significantly increase the risk of energy consumption and premature failure. If bearing with iron filings, burr, dust and other foreign matter to enter, will make the bearing noise and vibration during operation, even damage raceway and rolling body. So before the installation of bearings, must ensure that the installation surface and the environment clean. Diagonal contact ball bearing lubrication of work and life have very important influence. Grease made out of base oil, thickener and additive. The performance of the grease is mainly determined by the base oil. The basis of generally low viscosity oil is suitable for low temperature, high speed; High viscosity is suitable for high temperature, high load. Thickener and relationship with lubrication performance, thickening agent, water resistance to the water resistance of the grease. In principle, different brand of grease can't mix, and even the same thickening agent of grease, will also bring bad influence each other on the basis of different additives. INA bearing surface coated with anti-rust oil, must use clean petrol or kerosene cleaning carefully, then coated with clean, high quality or high speed high temperature lubricating grease before installation. Fully enclosed bearing not clean fuel. During the period of using, often should basic external conditions of INA bearings running monitoring, such as temperature, vibration and noise measurement, etc. These regular check will help identify potential problems and to prevent unexpected machine to suspend the phenomenon, make the production plan, improve plant productivity and efficiency. In the process of operation, bearing requires correct lubrication again, perfect its performance. Angular contact ball bearing lubrication method, divided into grease lubrication and oil lubrication. In order to make the INA bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. But there are grease lubrication can simplify the structure of bearing around specialty. Choose the right the right amount of lubricant, adopt the correct lubrication method for any bearing is vital to the success of the operation, this is because the angular contact ball bearing lubricant has three main functions: separation of contact surface, reducing friction; Heat dissipation; To prevent corrosion. In the applications of vertical slow roll, high temperature, shock, overload, low speed application environment makes the INA bearing is difficult to form good lubrication condition, bad environment and the impact of dust has worsened the lubrication conditions. Actual application result table, most of the roller bearing damage is the result of improper bearing lubrication. For slow roller bearing working condition of the application of this kind of bad, in the choice of lubrication system design, using circulating oil lubrication system is relatively effective, one side surface circulating oil can effectively take away most of the heat generated by the bearing is working as well as the external thermal radiation, on the other hand also can pass away circulating oil bearing within the tiny impurities, purify the bearing working environment. The working life of the seal of INA bearing roller mill bearing has great influence. It must prevent the lubricant from bearing leakage, must prevent outside pollutants from entering the bearing at the same time. Fine abrasive particles in the work environment, a large number of small hard particle is easy to enter the micro internal slow roller bearing, worse angular contact ball bearing work environment, reduces the lubricating effect, even in the raceway surface creasing, raceway surface spalling, pitting or reduce the working life of the bearing. Because of this, choosing the high reliability of the sealing parts, is very important to the working life of the bearing. In addition, multiple seal design and design, both inside and outside the roller pressure difference, can effectively prevent outside pollutants from entering the bearing inside.
