NTN bearing installed on the bearing performance and life

NTN 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. 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. Lubrication of NTN bearing 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. 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. After the NTN bearing installed, if not done carefully alignment, alignment can lead to bearing suffered 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. During the period of using, often should basic external conditions of bearing operation 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. NTN bearing lubrication method, divided into grease lubrication and oil lubrication. In order to make the 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. Hydraulic pump plunger pump bearing is the most important components of the bearing. Reduce the negative pressure in the bearing is to prevent the water into the basic requirements. Angular contact bearing load calculation. Oil for maintenance of locomotive bearing is very important.
