1. High hardness: The hardness of high carbon chromium bearing steel needle roller bearings is usually between 60-66 HRC, which provides good wear resistance and abrasion resistance, suitable for high-speed and high load bearing applications
2. Good corrosion resistance: After appropriate heat treatment and surface treatment, high carbon chromium bearing steel needle roller bearings can provide good corrosion resistance, making the material have long life and stability under harsh working conditions
3. Excellent cutting performance: This means it can be easily machined into bearing parts of various shapes and sizes, which is very important for production and manufacturers, making the production process more efficient and precise
4. Excellent fatigue strength: The microstructure and heat treatment process of high carbon chromium bearing steel can provide excellent fatigue strength, enabling it to maintain stable performance during long-term use
5. Reliable high temperature performance: able to maintain stable performance in high temperature environments, suitable for bearing requirements that can withstand heavy loads and high speeds in high temperature applications, such as power plants, metallurgy, and mining
