What is the difference between imported bearings and domestic bearings?

1. The accuracy of the bearing Although the dimensional deviation and rotation accuracy of domestic bearings are very close to those of imported bearings. However, there is still a certain gap in dispersion with German imported bearings. Foreign countries have already begun to study and apply such fine rotation accuracy indicators as "non-repeatable beating", but China's research in this area is still blank.

2. In terms of vibration, noise and abnormal sound Japan has introduced silent and ultra-quiet bearings, and the vibration extreme level of Chinese bearings is generally more than 10dB different from Japanese bearings.

3. In terms of life and reliability Taking deep groove ball bearings as an example, the life of foreign famous brand products is generally more than 8 times the calculated life (up to 30 times or more), and the reliability is more than 98% (or the pursuit of life with the main engine), while the life of Chinese bearings It is only 3 to 5 times the calculated lifetime, and the reliability is about 96%.

4. In terms of high-speed performance The DmN value of foreign brand-name products is 4 times 106 mm r/min, while Chinese bearings are only 2 times 106 mm r/min.
