SKF bearing corrosion control and elimination technology



SKF bearings use water-soluble cutting fluids, and users must work harder on machine maintenance and management to control the generation of corrosion and even eliminate corrosion. In order to prevent the water from corroding the metal surface, the machine tool should be fully lubricated and greased on important parts of the machine tool.
SKF bearings can have a long life under proper use. If damage occurs prematurely, it is most likely due to incorrect selection, improper use or poor lubrication.
Therefore, when installing the bearing, we need to record the type of machine, the installation location, the conditions of use and the surrounding fit. Through research to summarize the type of bearing damage, the use environment when the problem occurs, to avoid similar situations happen again.
Accurately control the concentration of the cutting fluid. When the machine is shut down, flush the surface of the machine with cutting fluid and open the machine cover to dissipate the humid air in the working area of ​​the machine. To prevent the occurrence of electrical corrosion, a layer of waterproof grease should be applied to the metal surface. Moreover, the machine tool should be grounded strictly. It is not enough to ground the electrical cabinet. To avoid the breeding and breeding of bacteria, the cutting fluid should be cleaned or replaced regularly, the chips should be removed in time, and soft water (pure water with low mineral content) should be used. Diluted the cutting concentrate.
In addition to excellent quality, imported bearings are also very precise parts. They are high-performance bearings. If they are used improperly during use, they will not achieve the expected performance results, and it is easy to damage the bearings. Already noted.
First, the use of installation should be carefully and carefully not allowed to force the stamping, it is not allowed to use vertical joints to knock the bearings, and the pressure is not allowed to pass through the rolling elements.
Second, use appropriate and accurate installation tools to use special tools as much as possible, and try to avoid the use of cloth and short fibers.
Third, try to keep the bearing and its surrounding environment clean. Even if the smiling dust that is invisible to the naked eye enters the bearing, it will increase the wear, vibration and noise of the bearing.
Fourth, to prevent the corrosion of the bearing When taking the bearing directly by hand, you should wash the liquid on your hand and apply it with high-quality mineral oil before handling. In the rainy season and summer, pay special attention to rust prevention. Under certain operating conditions, SKF bearings can achieve longer life than traditional calculations, especially at light loads. These special operating conditions are when the rolling surfaces (tracks and rolling elements) are effectively separated by a lubricant film and the surface damage caused by contaminants is limited. In fact, under ideal conditions, the so-called permanent bearing life is possible.
