Working Principle
Conical spring washers generate elastic preload force when compressed between the bolt head and the mounting surface. During operation, the washer maintains continuous clamping pressure to compensate for vibration, thermal expansion, and minor settling of connected components, helping prevent loosening and improving joint stability.
- Generates elastic preload under compression
- Maintains stable clamping force during operation
- Compensates for vibration and component movement
- Reduces risk of bolt loosening in dynamic environments
Load & Deflection Performance
The conical structure is engineered to provide controlled elastic deflection under compressive load, allowing the washer to maintain stable preload force and reliable spring performance during long-term operation. As load changes occur due to vibration, thermal expansion, or component settling, the washer continuously compensates for movement to help maintain fastening stability and reduce the risk of loosening.
Stable Load Distribution
The conical design distributes compressive force evenly, helping improve joint stability and reduce localized stress concentration.
Reliable Elastic Recovery
Maintains consistent spring performance after repeated compression cycles, ensuring continuous preload retention during operation.
Suitable for Dynamic Loading Conditions
Performs effectively in applications exposed to vibration, cyclic loading, shock, and repeated mechanical movement.
Installation & Assembly Benefits
Conical spring washers are designed for easy integration with standard bolts, nuts, and fastening systems, providing efficient installation while improving long-term fastening reliability. Their elastic preload capability helps maintain stable clamping force during operation, reducing the risk of loosening caused by vibration, thermal expansion, or repeated mechanical movement.
