⚙️Properties of carbon steel bearings:
The characteristic of carbon steel bearings is that they are inexpensive and the requirements for them in application scenarios are not very high. Their hardness, wear resistance, and lifespan are somewhat inferior compared to conventional bearing steel bearings.
1. Compared to bearing steel, the service life of carbon steel bearings is shorter.
2. Low-carbon steel is only carburized on the surface and then quenched, without being fully hardened. Its wear resistance is poor.
3. Carbon steel bearings have higher noise levels and can only withstand relatively small pressures. However, they can be used in places with relatively low hardness and maximum rotational speed.
The performance of the bearings depends on the usage environment. It's not that carbon steel bearings are inferior. It all depends on which machinery they are used in. For some machinery, high-end ones are not necessary; using carbon steel bearings is perfectly fine.

| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
