The disc spring, also known as Belleville washer or disc washer or conical spring washer.  The disc spring is a spring washer with a conical shape. The conical disc springs can be subjected to large loads or impacts with minor deflection, and the disc springs’ characteristics can be changed by itself or by stacking.

Characteristics of disc springs

High load capacity with a small deflection.

Better space utilization compared to other springs.

Excellent performance on dampening effect especially when stacked.

Standard dimensions can reduce costs.

High fatigue life.

Materials of disc springs

Spring steel 60Si2Mn、50CrVA, carbon steel, chrome vanadium steel, phosphor bronze, and stainless steel or special materials.

Corrosion Protective of disc springs

The surface treatments of disc springs are available to protect the disc spring against numerous working conditions.

Standard corrosion protection is phosphate and oiled. Other coatings like Mechanical Zinc Plating, Chemical Nickel Plating, Docromet / Geomet Coating are available.

Application of disc springs

Disc Springs for Actuators & Ball Valves

Disc springs for Switchgear Applications

Disc Springs for Windmills

Belleville Washers for Fasteners
