In recent years, the production scale of bearings in China has expanded rapidly, with the number of bearing enterprises approaching 2000, nearly half of which are large enterprises, with sales revenue exceeding 5 million. Since 2014, the development of domestic hardware and bearing industry manufacturing has been slow, and the technical level of bearing process equipment is low. Many large bearing enterprises still use traditional equipment as the main production force, which has greatly hindered the development of roller bearing product technology.

In fact, the overall growth rate of the bearing industry in China is not fast. However, with the growth of manufacturers of bearing fasteners, users have increasingly higher requirements for the accuracy, function, and type of bearing products. This has also evolved into a significant increase in the market demand for high-end bearings. In order to meet this demand, the bearing industry should vigorously promote the level and quality of bearing products.

There are many difficulties in the industry that have not yet been overcome in the related technology of bearing products. If the level and moral character of front bearing products are to be improved, it is necessary to face up to the progress of steel quality, and do a good job in the research and development of related technologies such as smoothing, cleaning, and abrasive tools. However, these related technologies in front of us have not met the requirements.

As a fundamental industry focused on the development of China, the bearing industry has certainly enjoyed a pleasant growth rate, but it has already possessed greater production capabilities. National policies have given strong support to the growth of the bearing industry, and under such circumstances, the economic scope of the bearing industry is gradually increasing. In the dynamic period yesterday, if the bearing industry wants to further grow, it will definitely enter the Internet e-commerce market.

Entering Internet e-commerce has also created a new market space for the bearing industry, effectively slowing down the phenomenon of excess capacity in the bearing industry. With the growth of Internet e-commerce, more market channels have been opened up, as the conservative Internet e-commerce format has become increasingly saturated, and the emerging mobile Internet market may become a new direction for the growth of the bearing industry.

The bearing is damaged and should be replaced.

2. The rolling bearing has too little grease, an appropriate amount, or impurities such as iron filings. The capacity of bearing grease should not exceed 70% of the total volume. Those with impurities should be replaced.

3. The shaft fits too tightly or too loosely with the bearing. If it is too tight, it should be reground, and if it is too loose, it should be inserted into the shaft.

4. The bearing fits too tightly or too loosely with the end cap. When it is too tight, process the bearing chamber, and when it is too loose, insert a steel sleeve into the end cover.

5. Poor assembly of motor end covers or bearing covers. Install the end cap or bearing cap lip in and flat, and tighten the screws.

6. The belt is too tight or the coupling is poorly assembled. Adjust the belt tension and align the coupling.

"The sliding bearing has too little lubricating oil, impurities, or oil rings are stuck.". Such as adding oil, replacing oil, repairing or replacing the oil ring.
