At that time, although the invention and application of bearings had been for some time, the industrial production of bearings had just started from scratch and was quite naive. The main features are:
1. The production scale is very small. A large factory has only a dozen to several hundred people, and the daily output is only a few to several hundred sets, which belongs to manual workshop production;
2. The equipment is simple, the technology is backward, and the production is mostly based on experience;
3. The material is mainly carbon steel, with low precision and high price;
4. There are few varieties and very limited uses. At that time, the bearing production technology was only in the hands of a few enterprises in Britain, Germany, Sweden and the United States.
