Bearing is one of the important parts of construction machinery, poor installation will affect its performance, fault and even cause the engineering machinery and equipment.
If the NSK bearings in the foreign body iron, burr, dust, will make the deep groove ball bearing noise and vibration when in operation, and may even damage raceway and rolling body. So before you install the NSK bearings, must ensure that the installation surface and the environment clean.
Work and life of the lubrication of the deep groove ball bearing has important effect. Grease is made of base oil, thickening agent and additive. Performance grease base oil mainly by the decision. Generally the low viscosity base oil used in low temperature, high speed; high - viscosity for high temperature, high load.
Thickening is also related to lubrication performance, thickening of the water resistance of the water - resistance grease decide. In principle, grease mix different brands, but, even with the grease thickener, also because of the different additives adversely affect each other. NSK bearing surface coated with anti-rust oil, must be carefully cleaned with clean gasoline or kerosene, lubricating oil and then coated with clean quality or high temperature can be installed. Sealed bearing without cleaning and oiling.
NSK bearing after installation, if not carefully tuned, straightening can lead to bearing subjected to additional loads, friction and vibration. These may be accelerated fatigue and reduced service life of deep groove ball bearings, and may damage the lifespan of the machine parts. In addition, vibration and friction may increase significantly increased energy consumption and premature failure risk.
During use, regular monitoring, basic external conditions of bearing operation, such as temperature, vibration and noise measurement, etc.. These regular checks for early detection of potential problems and prevent the emergence of beat all machine halt, make production plans to implement, improve plant productivity and efficiency.
In the process of operation, NSK bearings require proper lubrication once again, perfect its performance. Bearing lubrication method, divided into grease lubrication and oil lubrication. In order to make the NSK bearing play function very well, first of all, to choose suitable conditions, using the method of lubrication. If only consider lubrication, oil lubrication of lubrication advantage. But the grease around bearing structure can be simplified.
Components of hydraulic pump bearing plunger pump is the most important bearing bearings.reduce negative pressure in the NSK bearings are basic requirements for preventing water from entering. The load calculation of angular contact ball bearing. The locomotive bearing oil maintenance is very important.
