To maximize the service life of NTN import bearings

The service life of NTN import bearings in addition to depends on the quality of the product itself, there are some important factors. A, bearing type selection stage, need to consider many factors, Example: load, hardness, running environment, etc. ) First of all, a good NTN import bearings design will make bearing reaches its maximum life span. Second, the correct storage, NTN import bearings before installing the best shall be kept in their original packaging. Need to stay clean, no moisture, relatively constant temperature environment. NTN import bearings should stay away from dust, water and corrosive chemicals. Shaking and vibration may be forever on the mechanical properties of the damaged bearing, therefore in the process of processing and storage should avoid vibration. General bearing should be kept level, some of the heavier bearing long upright, will be deformation due to its own weight! Also, coated with grease, Or sealed) Bearing need to be careful, because the grease will change after long time storage density. When the bearing is used for the first time, there will be a certain degree of rotation noise. So, this kind of bearing on time should be to control according to the principle of first in first out! Third, clean, it is very important for rolling bearing. Imports NTN bearing ring rotation surface is very smooth, is sensitive to damage caused by pollutants. Impurity particles are influenced by the excessive rolling rolling element and partial pressure in the bearing, eventually lead to permanent material fatigue. Four, comprehensive equipment installation, bearing should use the right tool to install and remove cautiously, Can be dismantled reference bearing series video) 。 Should choose the right tools! Industry experts estimate that premature bearing failure, 16% were caused by incorrect installation. Generally a large number of installation, generally take appropriate bearing installation of equipment. But in the maintenance or replacement work, various environment! Recommend that the relevant drawings, maintenance manual, product manuals carefully have a look. Bearing components should also keep absolutely clean! Five, the careful installation and disassembly, once many times before about the installation (NTN import bearings You if you have a similar problem, here are some bearing on how to install) , again simple summarize: 1, don't put 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 the bearing. 2, do not use any hard tool ( Like a hammer, screwdriver, etc. , I have seen too many 'hard' with these two tools installed, too) Directly on the bearing surface, which can lead to bearing ring fault or broken. 3, general bearing not removed from the equipment, only larger bearings are removed for preventive maintenance. Disassembly process, first of all, you should use the right tools, make sure the adjacent components are not damaged! Six, right proper lubrication, lubricants can be isolated bearing surface, so as to reduce friction, protect the metal parts and prevent pollution and impurities. There are all kinds of grease which can be chosen by the different operating conditions. Because of the excessive rolling rolling parts, bearing lubricant subjected to mechanical stress for a long time, and especially for a long time in high temperature, damp or polluted environment, chemical properties of lubricant will change. These will be led to the decrease of the quality of the lubricant. So, to regularly for NTN bearing lubrication.
