    Theoretically, the service life of the rolling SKF imported bearings in the centrifugal pump is 20,000~80,000 hours, but the actual life depends on many factors-premature NSK imported bearing failure will lead to costly equipment shutdowns, and sometimes even lead to More serious consequences. SKF bearing experts from NKE (Austria) provided some simple but practical tips for optimizing the performance of SKF bearings.

    A satisfactory service life of SKF imported bearings begins with the correct selection of SKF imported bearings. From the beginning, SKF imported bearing designers have extended the service life and equipment performance of SKF imported bearings by choosing the correct SKF imported bearings for different applications. Many factors should be considered in this process, such as load, hardness, life prediction of NSK imported bearings, operating environment and so on.

Correct storage

    In principle, all SKF imported bearings should be stored in their original packaging before installation. They need to stay in a clean, moisture-free, relatively constant temperature environment. Rolling imported SKF bearings should be kept away from dust, water and corrosive chemicals. Shake and vibration may permanently destroy the mechanical properties of SKF imported bearings, so vibration must be avoided during handling and storage.

    Basically, all SKF imported bearings must be stored horizontally, because some heavier SKF imported bearings may be deformed due to their own weight after being placed vertically for a long time.

    Pre-greased (or sealed) SKF imported bearings require special care, because the density of the grease will change after a long period of storage. In this way, when SKF imported bearings are used for the first time, there will be a certain degree of rotating noise. Therefore, the shelving time of this kind of NSK imported bearings should be controlled according to the principle of first in, first out.

Clean

    Cleaning is very important for rolling SKF imported bearings. The surface roughness of the rotating surface and rolling elements of the NSK imported bearing ring is usually 1/10 μm. Such a smooth surface is very sensitive to damage caused by contaminants. The lubricating layer between the rotating surfaces is usually 0.2~1 μm. Particle-type impurities larger than the lubricant particle size will be excessively crushed by the rolling elements and generate local pressure in the SKF imported bearing steel, which will eventually lead to permanent material fatigue. In addition to this, the size of dust particles in the external environment can reach 10 μm, which can also cause damage to NSK imported bearings. Therefore, a clean and dust-free environment is very important for the storage and installation of SKF imported bearings.

Fully ready to install

　　 SKF imported bearings should be carefully installed and disassembled using appropriate tools. Industry experts estimate that 16% of premature SKF imported bearing failures are due to incorrect installation. For a large number of installations (such as in production equipment), the installation conditions are usually strictly controlled, and suitable SKF imported bearing installation equipment can also be used.
