Conical Disc Springs

Stacking Configurations

The strongest disc springs we offer for maintaining tension and separating components on shafts, under bolt heads, and at the end of valves. Unlike spring lock washers, they return to their original height again and again when decompressed. Also 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.

Steel—Strong and resilient, but best suited for dry environments since moisture will cause these springs to rust.

Corrosion-Resistant Stainless Steel—Won't corrode when exposed to moisture or mild chemicals, such as ammonia found in cleaning solutions. These springs compress more easily than steel springs, but they're not as strong.
