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


电梯-2

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

2. New energy and electricity

Wind turbine pitch system: resist extreme loads and ensure reliable blade positioning

High voltage circuit breaker: fast opening buffer, improve the safety of power equipment

3. Automobile and rail transit

Transmission clutch: optimize the smoothness of shifting, long-term partner of Volkswagen / BYD and other car companies

Braking system: high heat resistant disc spring group to ensure the stability of emergency braking

4. Precision instruments and automation

Elevator safety pin: instantaneous response overload protection, TUV/CE certification

Robot joints: Compact design reduces weight and improves dynamic response
