Extreme-Temperature Belleville Disc Spring
Manufacturer part: 97125K79
These springs withstand temperatures from -400° to 1100° F. All are 718 nickel, a high-strength, corrosion-resistant alloy that's also known as Inconel. Use them on shafts, bolts, and the ends of valves to maintain tension and separate components. Unlike Belleville washers, they return to their original height once the load is removed.Deflection is the distance a spring compresses under load. Flat load is the load at which the spring is completely compressed.Springs may be stacked to increase working load and deflection. In a nested stack, working load is multiplied by the number of springs used, while deflection remains unchanged. In an inverted stack, deflection is multiplied by the number of springs used, while the working load remains unchanged. In a nested and inverted stack, both load and deflection are increased.
