Also known as conical washers, these have a slightly cupped shape that gives them spring-like flexibility to grip tighter than split and tooth lock washers. They minimize loosening from wear, temperature changes, and vibration. Load-rated Belleville disc springs are also available.

18-8 stainless steel and 17-7 PH stainless steel washers have good chemical resistance and may be mildly magnetic. 17-7 PH stainless steel washers are stronger than 18-8 stainless steel washers.

No groove required—these rings have teeth that firmly grip the bore. Use them in unhardened shafts that are softer than the push ring. The metal must be soft enough for the ring to form an interference grip. Not recommended for use with nickel-, chrome-, or nitride-coated shafts.

17-7 PH stainless steel rings are high strength with good corrosion resistance. Rings are passivated for added protection against corrosion.

Made of stainless steel, these springs are more corrosion resistant than steel springs. Use them on shafts, bolts, and the ends of valves to maintain tension and separate components. Unlike Belleville washers, they return to their original height once the load is removed.

Deflection is the distance a spring compresses under load. Flat load is the load at which the spring is completely compressed.

Springs may be stacked to increase working load and deflection. In a nested stack, working load is multiplied by the number of springs used, while deflection remains unchanged. In an inverted stack, deflection is multiplied by the number of springs used, while the working load remains unchanged. In a nested and inverted stack, both load and deflection are increased.

Keep pipe flange connections sealed during demanding applications. When installed under flange bolt heads, these springs compensate for shock loads, vibration, and thermal expansion and contraction. All are stainless steel for corrosion resistance.

Multiple rows of waves allow these springs to handle higher loads than other similarly sized wave disc springs.
