1. High-Purity Bearing Steel Substrate
The substrate is produced from high-carbon chromium steel via ultra-high-purity smelting, giving it extreme hardness and fatigue strength. It endures high-frequency, heavy-load impacts without deformation or peeling, ensuring long service life.

2. Precision Heat Treatment Strengthening
Overall quenching and low-temperature tempering, together with surface carburizing/nitriding of key areas, reinforce the core and create a superhard, wear-resistant surface—significantly improving load-bearing capacity and wear resistance.

3. Low-Friction Optimized Design
High-precision polished raceways and rolling elements, combined with nanoscale smoothness, markedly reduce operating resistance and temperature rise while improving energy efficiency and smooth, quiet running.

4. Corrosion-Resistant Sealing with Collaborative Protection
Stainless steel variants or special coatings are used to withstand damp salt spray. A composite rubber/metal dust cover locks high-performance grease in for life, blocking moisture and impurities and ensuring long-term, low-noise operation inside.
