Manufactured and tested to strict U.S. military standards for material and construction. These disc springs are also some of the strongest in our offering. Unlike spring lock washers, they return to their original height again and again when decompressed. Commonly known as Belleville disc springs.

To increase working load or deflection, stack multiple springs. A nested stack increases working load; an inverted stack increases deflection. In a nested and inverted stack, both load and deflection increase. Multiply the original working load or deflection (depending on your configuration) by the number of springs to find your new total.
