its great technical limitations directly affect the precision of these bearings

Given the current legal system is not perfect the socialist market economy, and many consumers do not know how to identify the merits of the bearing, or lured by the low price, so that small manufacturers of counterfeit bearings and bearing flooded the market. According backing bearings to statistics, the current market, small manufacturers of bearings and bearing  counterfeit share of over 60% in some areas even more than 80% market share. However, because of its inherent quality and inferior bearing defects and low precision and great harm, giving users a huge loss.
1, due to raw material constraints, shoddy bearing hardness less than the national requirements. Deformation occurs during use, etc., which can affect their life, damage to other parts of the machine. In particular, some high temperature bearings and high-speed bearings, bearing hardness directly affect their life and the use of safety.
2, due to the small manufacturers and underground factories dipped fire technical limitations, and shoddy bearing Nga uneven heating temperature dipped in the fire, so that the impact of the precision Stainless steel slewing bearing of the bearing, the deformed and so on.
3, its great technical limitations directly affect the precision of these bearings, so that this problem can not be overcome as flawed, but the gap is not only directly harm precision machine parts, also makes bearings become more cumbersome handling things, and even can be installed without, the situation can not be unloaded, direct damage to the machine, delay hours.
4, some small manufacturers and illegal plants in order to reduce costs, the use of inferior steel, malleable iron, carbon steel and other raw materials, while reducing technology in the production process, in the course of these products prone to problems, and even direct the machine of equipment.
In order to protect their own interests, in addition to consumers and enhance their awareness of the law, but also learn to identify, select genuine bearings, thereby avoiding irreparable damage to the device.
