Jiangsu Sunzo Elastic Technology Co., LTD. | Focus on disc spring research and development for 20 years
The disc spring (Belleville Spring) was invented by French engineer Julien Belleville in the 19th century. Its unique conical disc structure endows it with high stiffness, minimal deformation, and strong cushioning capabilities, making it an indispensable precision elastic component in modern industry. As a domestic manufacturer of disc springs, Jiangsu Sunzo leverages its mature processes and innovative technologies to provide global customers with high-performance, long-life customized solutions.
Core advantages of disc springs
✅ High carrying capacity: provides greater elasticity per unit volume and saves installation space
✅ Precise pre-tightening: eliminate the clearance of mechanical parts and improve the stability of equipment operation
✅ Strong anti-fatigue: it still maintains its performance after millions of tests, and its life is far longer than that of ordinary springs
✅ Flexible combination: series/parallel use to adjust stiffness and load curve
Jiangsu Sunzo disc spring typical application field
1. High-end equipment manufacturing
Machine spindle: pre-tension compensation axial clearance to ensure machining accuracy
Industrial valves: high pressure resistant, corrosion resistant spring, adapt to the harsh environment of chemical pipelines
SUNZO has it’s own researching and development team and test center, has participate in rule-making of the latest national industry standards and the international ISO standards for disc springs.
