With the advent of the international tide, the domestic bearing code is gradually integrated with the SKF bearing code. The latest published national standards show that the domestic code is basically the same as the international ISO standard.
The mark on the bearing, such as the famous bearing of the domestic bearing, is that the Luoyang axis code is (LUO) and the Harbin bearing code is (HA) basically the same. Each bearing has a digital code indicating that the bearing type has a pinyin mark to represent the place of origin. If you want to be a person from the mechanical industry, you should know.
2, other aspects
Compared with domestic bearings, SKF bearings are generally better in materials than domestic ones. The heat treatment process is more advanced than domestic ones, with high manufacturing precision, more reasonable manufacturing and assembly processes, and long service life. Of course, the price is higher. And SKF bearings are generally more genuine, the most important thing is that SKF bearings are made in foreign countries. Haha, this is not to say that everyone can understand.
For the life, although the service life of SKF bearings is longer than that of domestic ones, if the ordinary machines are not very high in terms of precision, they can be made domestically. Now the quality of bearings produced by major manufacturers such as HRB and ZWZ is very good. Good. The price is also suitable, can also be used to live. But when the accuracy is required, it is still a good point of SKF.
