Extra-Flexible Notched Conical Disc Springs

Stacking Configurations |
With inner notches that flex easily, these springs compress over twice as far as standard conical disc springs. They return to their original height again and again when decompressed, unlike spring lock washers.
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.
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.
