Tempered Carbon Steel Shaft Sleeve Forgings for Wind Turbine Gearbox Drive Systems
Tempered Carbon Steel Shaft Sleeve Forgings for Wind Turbine Gearbox Drive Systems
Tempered Carbon Steel Shaft Sleeve Forgings are precision-engineered components designed to protect and align rotating shafts in steel mill drive systems. Manufactured from medium-carbon steel via open-die forging followed by tempering heat treatment, these sleeves provide critical wear resistance and structural support in high-temperature, high-vibration rolling mill environments.
Key Characteristics
