Product Description Product Description Spiral springs are precision-engineered components designed to function as balancing springs, particularly in applications involving rotational movements with smaller angles. These springs are specifically utilized to store mechanical energy, which is then effectively employed to generate a counterbalancing force or a self-aligning torque. This makes them ideal for systems requiring precise alignment or stabilization. One of the key characteristics of spiral springs is their nearly linear spring curve, which ensures consistent and predictable performance throughout their operational range. This linearity allows for accurate control and reliable functionality in various mechanical and industrial applications, making spiral springs a critical component in systems where precision and stability are paramount.Here's the updated table with **wire diameter** replaced by **material thickness**, which is more appropriate for certain types of spiral springs, especially those made from flat strips or ribbons:ParameterExample 1Example 2Example 3MaterialHigh-carbon steelStainless steel (AISI 302)Phosphor bronzeMaterial Thickness (mm)0.50.81.2Outer Diameter (mm)101520Inner Diameter (mm)5812Number of Turns101215Spring Rate (N/mm)0.20.50.8Load Capacity (N)51020Operating Temperature-20°C to +120°C-50°C to +200°C-40°C to +150°CWorkcraftCold-wound, heat-treatedPrecision-wound, polishedHot-wound, stress-relievedSurface FinishZinc-platedPassivatedNatural finishUsage/ApplicationSmall torque motorsMedical devicesPrecision instrumentsAdvantagesHigh durability, linear torqueCorrosion-resistant, preciseExcellent fatigue resistanceLimitationsLimited to small anglesHigher costNot suitable for high loads### **Key Notes:**- **Material Thickness**: Refers to the thickness of the flat strip or ribbon used to manufacture the spiral spring.
