A conical spring is a type of mechanical spring that is shaped like a cone, with the diameter of the coils gradually increasing or decreasing from one end to the other. Conical springs are typically made from materials such as steel or titanium, and they are commonly used in a wide range of industrial applications that require a spring with a specific load and deflection characteristics.

The cone shape of the spring provides several advantages over other types of springs. For one, the tapered shape allows for a more gradual and uniform distribution of stress across the coils, which can result in a longer service life and increased reliability. Additionally, the conical shape allows for a greater deflection range than other types of springs, making them ideal for applications that require a high degree of flexibility and shock absorption.
