NTN Bearing is one of the important parts of construction machinery, install the poor will affect their use of effects, and even cause the failure of the construction machinery and equipment.
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.
Extremely important impact on the operation and life of NTN Bearing lubrication. 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 additives different. Bearing surface is 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.
NTN bearings installed on the careful alignment, the alignment may cause the bearings subjected to the additional load, friction and vibration. These may accelerate fatigue and reduce the service life of bearings, and the period of use of other machine parts may be damaged. In addition, the increased vibration and friction may be greatly increased energy consumption and the risk of premature failure.
Bearing running external conditions during use, to regular monitoring, 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. NTN Bearing lubrication method, divided into grease and oil lubrication. To the bearing play function, first select the appropriate conditions of use, the purpose of lubrication method. If there is only a lubrication, oil lubrication lubrication dominant. Greased expertise can simplify the bearing surrounding structures.
The most important components of the hydraulic pump bearing piston pump bearings. Reduce the negative pressure in the bearing to prevent water from entering the basic requirements. Load calculation of the angular contact bearings. Locomotive bearing maintenance is very important to the oil.
