Belleville springs are designed to function very similarly to other springs, such as coil springs. However, their physical appearance differs from that of a coil spring. Belleville springs are generally flat, like that of a washer, but are classified as conical springs, since their centers are raised, which creates a cone. This cone shape is what gives a Belleville spring its heavy-duty strength. In contrast, a coil spring are typically comprised of coiled metal and are components which create energy when the ends are pushed together. They are commonly used in applications that require a shock absorber, such as a mattress and a bike or car shock.
Choosing a Belleville Washer Spring
A Belleville washer applies uniform pressure to connections instead of at a single point. With Belleville washers, there is a wide variety in load, deflection, size, coating, and applications. There are three factors that should be considered before choosing a Belleville washer, these include:

Our Belleville springs are manufactured from a wide range of materials to fit your specific project requirements. Our technical specifications guide provides all the information that you need regarding our standard tolerances, units of measure and torque calculations.
A single Belleville spring has a specific load and deflection. Belleville springs in stacked arrangements provide increased load and/or deflection. Two springs stacked in parallel doubles the load of a single spring with no increase in deflection. Two springs stacked in series doubles the deflection of a spring with no increase in load. The parallel-series combination as shown below results in the load of two springs and the deflection of two springs.
