Product Description
In axial preload applications, confusion often arises between "disc springs" and "Belleville washers"—a distinction rooted in regional terminology rather than technical differences. These components are functionally identical: the term "Belleville washer" honors 19th-century French inventor Julien Belleville, while "disc spring" is the modern industrial designation.
SUNZO Disc Springs (Belleville washers) are precision-engineered to deliver consistent axial preload in critical applications, leveraging their conical geometry to achieve high stiffness (5-50 N/mm) with minimal axial space requirements—typically 30-70% smaller than coil springs of equivalent load capacity.
Material & Performance: Constructed from materials ranging from high-carbon steels (1074, 65Mn) to superalloys (Inconel 718), these components maintain stable performance across temperature ranges of -270°C to 650°C and exhibit exceptional fatigue life (>10⁸ cycles at 70% of yield strength).
Their non-linear load-deflection characteristics allow for precise tuning:
- Parallel stacking increases load capacity for heavy-duty applications like bolted flange connections
- Series stacking enhances deflection for shock absorption in automotive suspension systems
Unlike traditional flat washers, SUNZO Disc Springs offer engineered flexibility through modular combinations:
- Nested stacks for variable stiffness
- Coated variants (PTFE, zinc plating) for corrosion resistance
- Precision-machined edges for uniform load distribution
Compliance: DIN 2092, ISO 16148 ensuring interchangeability
Custom Configurations: OD 5mm-300mm, thickness 0.2mm-10mm to address unique industrial requirements
For mission-critical preload applications—from turbine engine bolt retention to semiconductor manufacturing equipment—SUNZO Disc Springs provide unmatched reliability, backed by rigorous quality testing including:
- Ultrasonic flaw detection
- Load-deflection curve validation (±3% tolerance)
- Salt spray testing (ASTM B117)
When precision, durability, and space efficiency matter, the distinction between "disc spring" and "Belleville washer" fades; what remains is a proven solution engineered for optimal axial preload performance.
