Product Description
Bearing Disc Spring Fatigue Resistance
Our Bearing Preload Disc Spring (grooved/grooveless series) exhibits exceptional fatigue resistance, engineered to excel in high-speed continuous bearing operation across precision machinery, automotive powertrains, and industrial spindles.
Ultra-High Cycle Durability
Engineered for high-speed continuous bearing operation in extreme conditions, these disc springs deliver reliable performance in demanding applications.
Optimized Geometric Design
- Annular geometry with stress-relieved fillets (R0.3-R0.8mm)
- Uniform wall thickness (±0.005mm) eliminates stress concentration points
- Designed for high-frequency preload cycling up to 500Hz
Premium Material Construction
| Material | Composition | Heat Treatment | Properties |
|---|---|---|---|
| 50CrVA | 1.05%C-0.8%V-0.25%Mo | Quenched at 860°C, tempered at 420°C | HRC 45-50 hardness, 1800MPa tensile strength |
| 60Si2MnA | 0.6%C-2.0%Si-1.0%Mn | Quenched at 870°C, tempered at 480°C | Superior elastic limit (≥1200MPa) |
