1:  bearing deposit:
1. bearing the correct storage method is to  bearings placed in horizontal position, bearing ring should be supported throughout the side. If the bearing to the location of the vertical display, due to the relatively small thickness of bearing ring, bearing rings and rolling bodies may lead to bearing the weight of the permanent deformation.
2. Stockroom of the relative humidity of not more than 60%, little change in temperature, the bearings can be a very good long-term preservation in the original package. With seals or dust cover over a long period after the deposit of the bearing, bearing the characteristics of grease may be affected. Taken out in the original packaging after the bearings, should be properly protected to prevent erosion and pollution.
2: slightly  bearing counterfeit pseudo-harm:
1, due to the small factories and underground factories dip fire technical constraints, and inferior bearing Nga dip fire uneven heating temperature, thereby affecting the precision bearings, deformed and so on.
2, due to raw material constraints, the hardness of counterfeit bearings fail to national requirements. Deformation occurs in use, etc., thus affecting its service life, damage to other parts of the machine. In particular, some high temperature bearings and high-speed bearings, bearing a direct impact on the hardness of their life and the use of security.
3, some small factories and illegal processing plants in order to reduce costs, the use of low-quality steel, malleable iron, carbon steel and other raw materials, while reducing technology in the production process, these products use the process prone to problems, and even directly to machinery and equipment obsolescence.
In order to safeguard their own interests, in addition to consumers to enhance their awareness of the law, but also learn to identify, select genuine bearings, so as to avoid causing irreparable equipment damage.
4, the technical constraints of its huge direct impact on the precision of these bearings, so that this issue has become unable to overcome flawed, but the gap is not only directly damage precision machine parts, but also makes loading and unloading to become more cumbersome bearing things, even can not install, can not unload the case, direct damage to machinery, delays in work hours
