Springs

Confined-Space Conical Compression Springs

Install these springs in tight spots. When pushed together, the coils nest within each other.

Belleville Disc Springs

Use these steel springs in noncorrosive environments.

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.

Extreme-Temperature Belleville Disc Springs

These springs withstand temperatures from -400° to 1100° F. All are 718 nickel, a high-strength, corrosion-resistant alloy that's also known as Inconel.

Belleville Disc Springs for Ball Bearings

Install these springs, also known as bearing preload washers, against ball bearings to reduce noise and unwanted movement along the shaft.

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.
