Disc Springs

Corrosion-Resistant Belleville Disc Springs

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.

Belleville Disc Springs for Flange Bolts

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.

Mil. Spec. Belleville Disc Springs

These springs meet MIL-W-12133.

Corrosion-Resistant Stacked Wave Disc Springs

Made of 17-7 PH stainless steel with multiple rows of waves, these springs are more corrosion resistant than steel springs and handle greater loads than standard wave disc springs.

Notched Disc Springs

Notches make these springs more flexible than Belleville disc springs and allow liquid to flow around the spring, even while it's in use.
