How to prolong the service life of NSK bearing import

Theoretically the service life of NSK import centrifugal pump in the rolling bearing is 20000 ~ 80000 hours, however, the actual life depends on many factors - — NSK import premature bearing failure can lead to high cost equipment to cease, and sometimes even will lead to more serious consequences. 设立了( Austria) NSK import bearing the company's experts offered some simple but practical NSK import bearing performance optimization techniques. Satisfactory NSK import bearing NSK import bearing service life started in the right choice. NSK import bearing from the beginning, the designer through the NSK import for different application to select the correct bearing NSK import bearings to prolong service life and equipment performance. This process should consider many factors, such as load, hardness, NSK import bearing life prediction, running environment, etc. Correct storage, in principle, all NSK bearing import before installation should be stored in their original packaging. They need to stay clean, no moisture, relatively constant temperature environment. NSK import rolling bearing should stay away from dust, water and corrosive chemicals. Shaking and vibration may be forever NSK import bearing damage mechanical properties, so the vibrations must be avoided in the process of handling and storage. Basically, save all import NSK bearing must be level, because some of the heavier NSK bearing import long upright, may deformation due to its own weight. In advance (coated with grease Or sealed) NSK bearings imported need special care, because the grease will change after long time of storage density. NSK import bearings used for the first time, so that when there will be a certain degree of rotation noise. Therefore, the import NSK bearing on time should be controlled according to the principle of first in first out. NSK import clean clean for rolling bearing is very important. NSK bearings imported ring rotation surface and the surface roughness of the rolling element is usually a 1/10 microns, such a smooth surface is sensitive to damage caused by pollutants. Lubrication layer between the rotation surface usually is 0. 2 ~ 1 microns, is greater than the lubricant type size particles of impurities are influenced by the excessive rolling rolling element and partial pressure in the NSK bearing steel imports, eventually lead to permanent material fatigue. In addition to this, the external environment of dust particle size can be up to 10 microns, also can cause damage to NSK bearing import. Therefore, clean and dust-free environment for storage and installation of NSK bearing import is crucial. NSK import bearings should be fully prepared to install use appropriate tools to install and remove cautiously. Industry experts estimate that premature failure situations of NSK bearing import 16% was due to incorrect installation. For large installation ( In the production plant, for example) Installation, usually we will strictly control conditions, can also use appropriate NSK bearing import equipment installation. But, in the maintenance or replacement work, the environment is varied. Therefore, in order to ensure the longest imported NSK bearing life, full preparation is necessary to import NSK bearing installation. First, the relevant documents, such as drawings, maintenance manual, product manuals, etc need to carefully study. Next, all import NSK bearing components, such as shaft, spacer ring, must be perfectly clean, cover, washer, etc from pollution. The condition of adjacent parts also check carefully. According to the different applications and the erection and dismantling of cautious NSK import bearing size and type, select the appropriate installation method ( Mechanical or hydraulic) And tools. NSK import bearing installed here is some basic principles: 1. Don't impose on rolling element installed power, this could easily lead to the rolling element and contact area of local overload, which can lead to premature failure of NSK bearings imported. 2. Do not use any hard tool ( For example, a hammer, screwdriver, etc. ) Direct knock on import NSK bearing surface, which can lead to import NSK bearing ring fracture or fracture.
