SKF bearings can have a long life under the correct application. If it is a premature damage, it can be because of the wrong selection, improper use or smooth formation.
Therefore; when installing the bearing; we need to record the variety of the machine; the device parts; the operating conditions and the surrounding cooperation. After the study to summarize the type of bearing damage; the use of the environment when the problem occurs; to avoid similar situations.
Accurately control the concentration of cutting fluid; when the machine is shut down; use the cutting fluid to clean the surface of the machine; and open the machine cover; to disperse the humid air in the working area of ​​the machine. To avoid the occurrence of electric corrosion; The upper layer of waterproof and smooth grease should be grounded strictly; the grounding of the electrical cabinet is not acceptable; to avoid the proliferation and reproduction of bacteria; the sanitary fluid should be replaced or replaced regularly; the chips should be removed in time; and soft water should be used. (Pure water with low mineral content) dilute the cutting concentrate.
In addition to the excellent quality of imported bearings; it is also attributed to very fine parts; it is a high-performance bearing; if it is used improperly in the application process; not only does not achieve the expected function; and it is very simple to damage the bearing; we must be smooth in terms of smoothness Has been focused on.
First, the use of the device should be carefully and carefully not allowed to force the stamping; vertical joints are not allowed to be used; the pressure is not allowed to pass through the roll.
Second, use appropriate and precise devices to try to use special things; try to avoid the use of cloth and short fibers and the like.
Third, try to adhere to the bearing and its surrounding environment, even if the invisible shallow dust enters the bearing; it will also add bearing wear; oscillation and noise.
Fourth, to avoid the corrosion of the bearing directly when taking the bearing by hand; to wash the liquid on the hand; and apply high-quality mineral oil before operation; especially in the dry season and summer to pay attention to rust. In a special Under operating conditions; SKF bearings are able to obtain a better life than traditional accounting; especially under light load conditions. These special operating conditions are; when the rolling surface (track and roll) is effectively separated and constrained by a smooth oil film The appearance of the pollutants can be damaged. In fact; under the ambition of the conditions; the so-called Eternal Bearing life is ok.
