Disc Spring Washer (DIN6796) – Belleville's Innovation
The Disc Spring Washer (DIN6796), officially classified as the Belleville washer, represents French engineer Julien Belleville's late 19th-century innovation that transformed industrial safety by revolutionizing bolted connection reliability.
Engineering Excellence
Engineered specifically to counteract spontaneous loosening in critical fastener applications, this precision component adheres strictly to the DIN6796 standard. It undergoes rigorous testing for material integrity, dimensional accuracy, and consistent performance metrics.
Technical Specifications
- Materials: High-carbon spring steel 70#/72B or corrosion-resistant SUS304/SUS316 alloys
- Temperature range: -40°C to 200°C
- Standard compliance: DIN6796
- Frustoconical disc geometry for exceptional elastic recovery
Performance Advantages
The Belleville washer's defining frustoconical disc geometry delivers exceptional elastic recovery, generating a sustained preload force that dynamically absorbs vibrational energy, compensates for thermal expansion/contraction cycles, and resists mechanical shock.
Unlike conventional flat washers, the Belleville washer's non-linear load-deflection curve ensures clamping force stability even during micro-movements, preventing rotational loosening and fatigue-induced joint failure.
Application Areas
Aerospace engine components subjected to extreme G-forces
Medical diagnostic equipment requiring precision
Heavy machinery in mining operations
Automotive powertrain integrity under thermal stress
Operational Benefits
- Exceptional resistance to wear, chemical corrosion, and oxidation
- Extended service life with minimal maintenance requirements
- Reduces unplanned downtime and lowers lifecycle costs
- Mitigates catastrophic failure risks in dynamic systems
Transform your bolted connections from potential weak points into pillars of industrial safety and reliability with Belleville's century-old innovation.
