At present domestic bearing market chaos, all kinds of bearings manufacturers and underground black factory spread over, and shoddy bearing is full of the market, it is difficult to obtain the safeguard the rights and interests of consumers. In general, the current domestic market basically has the following kinds of bearing:

1, national fixed-point bearing manufacturer and meet the national standard of the bearing manufacturer product, called quality goods bearing, the main ha, watts, los, northwest four national fixed-point bearings manufacturers and other parts of the bearing. The factory has a perfect management system and strict quality supervision system, and have level of technology, for example quenching, grinding technology is other manufacturer place not break through. The enterprise products tend to have good precision and quality assurance, and were more strict and perfect after sales service system. In our products generally caused by the users are one hundred percent of the compensation for loss promise, and that is other manufacturer place does not have.

2, the precision can not reach the requirements of the state, the product of small manufacturer. These small manufacturers with lower cost, so in the existing market is formed its own price advantage. But because the country fixed unit of special steel bearing the supply quantitative, make raw materials become these manufacturer the first bruising; Second, because of the high cost of some equipment, the technical level was also severely limit, so these manufacturers even pay attention to quality also can not reach the country the precision of the designated factory. And precision and direct restricting its use range and the using life. And for the products sold only limited after-sales service, without any compensation commitment.

3, illegal small factory or underground workshop by the production of products. At present, the domestic market of producing phenomenon seriously, shandong linqing, hebei linyi, heibei baoding (radical county) there are fake and inferior bearing production base. These manufacturers manufacture and sell inferior bearing, with iron, carbon steel bearing (hardness is not enough), trademark infringement, the inferior bearings, small plant bearing a giant trademark, counterfeit famous companies of the product packaging, certificate . These type of underground black factory is take the low price to impact the market, and to bearing don't know much about consumers more easily to be these bearing the temptation of the low price, and these factory more do not have bearing factory production technology and capability, plus cut corners of the production process, make these bearing precision lower, more difficult to ensure quality, become a bomb on the machine, damage to equipment, and even make equipment scrap. These bearings after-sales service and quality to the solution of the problem is mentioned.

 
4, renovation bearing. Some small processing factory will purchase of waste bearing to the new wrot, grinding, repair, and then sell with new packaging. It is self-evident that the quality of products and the precision are more difficult to guarantee.
