Product Description
Bearing Disc Spring Fatigue Resistance - Ultra-High Cycle Durability for High-Speed Continuous Bearing Operation in Extreme Conditions
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.
Advanced Engineering Features
- Optimized annular geometry with stress-relieved fillets (R0.3-R0.8mm)
- Uniform wall thickness (±0.005mm) eliminates stress concentration points
- High-frequency preload cycling capability (up to 500Hz)
Premium Material Construction
- 50CrVA alloy steel (1.05%C-0.8%V-0.25%Mo)
- 60Si2MnA alloy steel (0.6%C-2.0%Si-1.0%Mn)
Proprietary Heat Treatment
- 50CrVA: 860°C quenching + 420°C tempering → HRC 45-50 hardness, 1800MPa tensile strength
- 60Si2MnA: 870°C quenching + 480°C tempering → ≥1200MPa elastic limit
Performance Specifications
- Fatigue life exceeds 10⁷ cycles at 40% of ultimate load
- Preload force retention >95% after 10⁶ compression-rebound cycles (ISO 10243)
- Uniform load distribution (±3% variance) in parallel stacked configurations
- Load multiplication ratios: 2.5-5.2x at equivalent displacement
- Stable preload for high-speed bearings up to 25,000 RPM
Field validation confirms no measurable deformation or performance degradation after 20,000 hours of continuous operation in automotive engine timing systems and precision grinding machines.
