Belleville Springs are metal compression springs conically formed from a washer of spring steel material. The distinct advantage is the generation of high force in a very short spring length and minimal movement when compressed. Belleville's conical shape gives an even annular loading and it is ideal for use in modular systems of construction.

• Ideal for applications where a large load is required in a small space
• Will return to their original free height over repeated loading
• Reduces the size of mated components, reduce machining time to create those mated components

Belleville Springs Can Be Stacked as Follows

• Series: Provides the load of a single disc spring while offering the combined deflection of the total number of springs stacked
• Parallel: Provides the deflection of a single disc spring while offering the combined load of the total number of springs stacked
• Series-Parallel: Provides both increased load and deflection

Materials Used in Belleville Springs

• 1074 High Carbon Steel: commercial grade, hard steel, ASTM A684
• Type 302 Stainless Steel: corrosion resistant, ASTM A313
• 50 CrV Chrome Vanadium: has a high surface quality and are suitable for applications up to 425 F
