1. Feel the quality of SKF Bearing through the surface
According to sales experience, In Testing many customers say that as long as the bearing surface is bright, it is of good quality, which is wrong. The brightness of SKF bearing surface should be a kind of dark brightness.
The reason for this dark brightness is whether the steel used by SKF Bearing meets the In Testing standard and its grinding process and cutting fluid, mainly the first two items.
2. Whether the chamfer is bright
The chamfer of SKF Bearing does not determine the quality of the bearing, but reflects the processing method of the bearing.
The chamfering is black, which means that after quenching and other heat treatment, the hardness of SKF Bearing is increased. In Testing However, some people think that the chamfering is black, which is not completely processed. This is a misunderstanding.
3. The integrated cage is better than the two bodies. Although the new technology uses the In Testing integrated cage, it only saves materials, and its performance on rotation is worse than that of the two bodies.
In general, the service life of SKF Bearing is related to three factors. One is the quality of SKF Bearing itself. The second is the use environment. The third is the installation method
Bearing is one of the important parts of construction machinery. In Testing Poor installation will affect its use effect and even cause the failure of construction machinery equipment.
If iron filings, burrs, dust and other foreign matters enter the IKO bearing, the bearing will produce noise and vibration during In Testing operation, and even damage the raceway and rolling element. Therefore, before installing IKO bearing, it is necessary to ensure that the installation surface and installation environment are clean.
Lubrication has a very important impact on the operation and service life of bearings. Lubricating grease is made of base oil, thickener and additives.
The performance of grease is mainly determined by base oil. In Testing Generally, base oil with low viscosity is suitable for low temperature and high speed; High viscosity is suitable for high temperature and high load.
The water resistance of thickener determines the water resistance of grease. In principle, greases of different brands cannot be mixed, and even greases with the same thickener will have bad effects on each other due to different additives.
The surface of IKO bearing is coated with antirust oil, which must be carefully cleaned with In Testing clean gasoline or kerosene, and then coated with clean, high-quality or high-speed and high-temperature lubricating grease before installation and use. Totally enclosed bearings do not need to be cleaned and oiled.
After the IKO bearing is installed, if it is not carefully aligned, the alignment may cause the bearing to suffer additional load, friction and vibration. These may In Testing accelerate fatigue and reduce the service life of IKO bearings,
and may damage the service life of other machine parts. In addition, increased vibration and friction may greatly increase energy consumption and the risk of premature failure.
During use, the basic external conditions of bearing operation should be monitored frequently, such as temperature, vibration and noise measurement.
These regular inspections will identify potential problems as soon as possible, prevent unexpected machine stoppage, realize the production plan and improve the productivity and efficiency of the plant.
In the process of operation, IKO bearing requires correct re lubrication to perfect its performance. IKO bearing lubrication methods are divided into grease lubrication and oil lubrication. In order to make IKO bearing function well,
first of all, choose the lubrication method suitable for use conditions and purposes. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing.
The bearing of hydraulic pump is an important component of plunger pump Reducing the negative pressure in IKO bearing is the basic requirement to prevent water from entering Load calculation of angular contact bearing The oil supply and maintenance of locomotive bearings is very important
