NTN import the service life of the bearings in addition to the quality of the product itself depends on the outside, and some important factors.

A, bearing type selection stages, need to consider many factors (example: load, hardness, running environment, etc), good NTN import bearing design first will make bearing reached its maximum life values.

Second, the correct storage, NTN import bearing before installing the best should be kept in their original package. Need to stay clean, no moisture, relatively constant temperature environment. NTN import bearing should stay away from the dust, water and corrosive chemical substances. Shaken and vibration may never destroy bearing mechanical properties, so in processing and storage process should avoid vibration.
General level of the bearing should be preserved, some heavier bearing a long time after leaving the vertical, because of their weight and will transform! Also, coated with grease (or sealed) bearing should be especially careful, because the grease after a long time after storage density will change. When bearing is used for the first time, there will be a certain degree of rotating noise. So, this kind of bearing time should be shelved by advanced first out principle to control!

Three, clean, the rolling bearing is very important. NTN import bearings the rotation of the ring is very smooth surface, damage of pollutants are very sensitive. Particles will be rolling of components of the impurities in bearing and excessive rolling from local pressure, will eventually result in permanent material fatigue.

Four, the overall equipment to install, bearing should use the right tools carefully install and remove (can reference bearing the removal of series video). Should choose the right tools! Industry experts estimate that bearing early failure, 16% was due to improper installation cause. Generally a large installation speaking, will generally take appropriate bearing installed equipment. But in the maintenance or replacement work, environment variety! Advise you, relevant drawings, maintenance manual, product manual carefully look at it. Bearing components should also keep absolutely clean!

Five, the carefully install and remove, many times before about NTN import bearings installation (all have similar problems such as, here are some bearing installed articles), again a summary: 1, do not put in the rolling element installed power, it is easy to cause the rolling element and a circle of the interface partial overload, leading to premature failure of the bearing. 2, don't use any hard tools (such as the hammer, a screwdriver, etc, I have seen too much with these two tools "hard" installation, strong) direct knock in the bearing surface, it will lead to a bearing the fracture or broken ring. 3, general bearing will not come down from the equipment, only larger bearings will for preventative maintenance and come down. Remove the process, should first use the right tools, to ensure that no damage in the adjacent parts!

Six, the correct proper lubrication, lubricant can isolation bearing surface, thus reducing friction, protection and to prevent pollution metal parts and impurities. There are all kinds of grease for different operating conditions to choose. Because of the excessive rolling rolling parts, bearings lubricant endured long mechanical pressure, and especially the long hours in the high temperature, moisture or the polluted environment, lubricant to the chemical will change. These will lead to lubrication quality decreased. So, want to periodically to NTN bearings of lubrication again.
