Disc Spring Stacks vs. Coil Springs
- High spring load with small spring deflection
- Better space utilization than with other spring types
- High fatigue life and low creep tendency with correct dimensioning
- Disc springs allow nearly any kind of characteristic curve
- Modular construction: Different combinations of disc springs show different characteristic curves including parallel stack and series stack
Advantages of China Disc Springs, Inc.
- Engineering & designing assistance
- Raw material from own cold rolling mill up to 6mm
- Own tooling shop
- Complete inhouse-production from raw material to finished disc spring
- Shot peening as a standard process for increased fatigue life
- Customer oriented service (e.g. stack pre-assembling)
- Special material for specific applications
- Various protective coating
- Own test laboratory
- Self-centering stacks do not need any additional guiding. They reduce friction and are applicable for disc spring dimensions greater than 200 mm OD
