As an industrial grain, bearings have existed since ancient times and have been used to today's society. They have more types, higher precision and higher technology and quality. However, many factory teachers are still difficult to judge whether they are high-quality bearings. Even if they are not paid attention to during installation, they will damage these bearings. Finally, they will be labeled with a hat of poor quality, Today, let's talk about some problems of bearings
First of all, let's understand some trends of domestic bearings. Bearings are mainly divided into three categories: domestic bearings, imported bearings and Shanzhai bearings. More than 50% of the main high-end manufacturers and factories in China are monopolized by foreign bearings, while 30% of the medium and low-end markets basically controlled in China can buy three to 10 domestic bearings in terms of price, If you don't talk about the fake products and make money, it will disrupt the order of the whole market. Of course, if you do so, you will make money. If you don't do well, the people will be miserable
Many people don't really understand foreign bearings: they are mainly divided into original imported bearings, provided that they must have the customs declaration form and certificate of origin. Domestic processed products, bearings pasted with foreigners, may be polished by domestic factories. At most, heat treatment and other parts are purchased and assembled by themselves, Another is to avoid being fooled into buying fake bearings in order to get cheap. It's really a loss and a loss. Especially when installing bearings, remember to choose appropriate bearings. Don't fail to install them and knock them with a hammer. It's easy to break the cage and outer ring. Let's tell you a few small ways. The first is to use lubricant and turn them in while lubricating, The second method is to grind the sanding paper and you can easily install it. Remember to be gentle with the bearing
The most important thing of bearing is steel and heat treatment. Because the impurities in domestic bearing steel cannot be completely removed during treatment and training, there is still a certain difference in quality between domestic and foreign steel. Secondly, it is really good when grinding by process, but when grinding in batch, because of the loss of equipment, the grinding cannot be accurate, Finally, heat treatment has always been the object of our study. Good bearings can only be known by looking at materials and services based on our own experience
