Double-Layer Spring Washer Manufacturer - Heavy-Duty Anti-Loosening Washer GB/T7244 High Elasticity - Customization Supported

The double spring washer is a high-performance anti-loosening washer. Its structure consists of two standard spring washers stacked opposite each other, with a double "V" shaped elastic structure in the cross-section. This washer meets the requirements of national standards (GB/T 7244) and American standards (ANSI B18.21.1), and is indispensable in high-vibration applications such as heavy machinery, rail transportation, and high-voltage equipment. It generates continuous preload through double elastic deformation, providing excellent anti-loosening and vibration-resistant performance. To enhance the washer's elasticity and fatigue strength, we can use carbon spring steel and perform quenching and tempering treatment, or apply anti-corrosion processes such as phosphating and blackening to the washer surface. This significantly improves its anti-loosening life and corrosion resistance.
