Belleville Springs
Belleville springs, also known as Belleville disc springs, are a type of conically shaped spring that can be loaded along its axis either statically or dynamically. They are well-regarded for their ability to handle large loads with minimal deflection and for their compact size, making them ideal for various industrial applications.
At HEGONG SPRING ®, we take pride in offering a diverse range of Belleville springs to meet various industrial needs. Our Disc Spring includes Belleville Disc Springs, Disc Spring Stacks, Corrosion Resistant Disc Springs, High Temperature Disc Springs,Cryogenic Disc Springs, Disc Springs for Ball Bearings.The primary advantages of our Belleville springs lie in their longevity, robust construction, and surface treatments that enhance durability and performance.
Characteristics of Belleville Springs
1. High Spring Force: Belleville disc springs can generate high spring forces relative to their size, making them ideal for applications where space is limited but strong spring action is required.
2. Compact Design: Due to their conical shape, Belleville springs offer a compact design, allowing for efficient use of space in mechanical assemblies.
3. Stacking Capability: Belleville springs can be stacked in series to increase the spring force or parallel to increase the deflection range, providing flexibility in meeting specific application requirements.
4. High Fatigue Life: When properly designed and manufactured, Belleville springs exhibit a high fatigue life, ensuring long-term reliability and performance in demanding environments.
5. Resilience to Axial and Radial Loads: Belleville disc springs can accommodate both axial and radial loads, making them suitable for applications where dynamic forces may be present.
Belleville Springs for Different Applications
Belleville springs are widely selected where conventional spring designs cannot provide the required force within the available axial space.
| Application | Function of Belleville Springs | Important Selection Factors |
| Industrial Valves | Maintain preload and sealing force | Pressure, temperature, material |
| Bearings | Provide axial preload | Load, deflection, installation space |
| Clutches & Brakes | Apply or release axial force | Fatigue cycles and load curve |
| Heavy Machinery | High-force loading and compensation | Load, shock and fatigue life |
| Petrochemical Equipment | Maintain force under demanding service conditions | Corrosion, temperature, pressure |
| Power Equipment | Preload and compensation | Temperature and long-term stability |
| Machine Tools | Compact preload and movement control | Accuracy, load and deflection |
| Energy Equipment | High-force spring loading | Temperature, corrosion and fatigue |
For critical applications, spring selection should be based on the actual working conditions rather than simply choosing the closest standard dimension.

Materials Used in Belleville Springs
●Carbon Steel
Carbon steel is one of the most commonly used materials for Belleville springs. It offers excellent strength and durability at a relatively low cost. Carbon steel Belleville disc springs are suitable for general-purpose applications where high load capacity and resistance to wear and fatigue are required. However, they may be prone to corrosion if not properly coated or treated.
●Stainless Steel
Stainless steel is widely used for Belleville disc springs in applications requiring corrosion resistance. Its superior resistance to rust and oxidation makes it ideal for use in harsh environments, such as marine, chemical, and food processing industries. Stainless steel Belleville disc springs also maintain their mechanical properties at elevated temperatures, adding to their versatility.
●High-Temperature Alloys
For applications involving extreme temperatures, high-temperature alloys such as Inconel, Hastelloy, and Nimonic are often chosen. These materials provide exceptional performance under thermal stress, maintaining their load-bearing capacity and resistance to creep and fatigue even at high temperatures. They are commonly used in aerospace, power generation, and high-performance automotive applications for Belleville disc springs.
●Alloy Steel
Alloy steel, often containing elements like chromium, molybdenum, and vanadium, enhances the mechanical properties of Belleville disc springs. These materials offer a good balance of strength, toughness, and wear resistance. Alloy steel Belleville springs are suitable for high-stress applications and can be heat-treated to further improve their performance.
●Phosphor Bronze
Phosphor bronze is chosen for its excellent fatigue resistance, wear resistance, and corrosion resistance, especially in environments exposed to salt water or chemicals. Belleville disc springs made from phosphor bronze are typically used in electrical applications due to their non-magnetic properties and good conductivity.
●Custom Coatings and Treatments
To enhance the performance and longevity of Belleville disc springs, various coatings and surface treatments can be applied. Common treatments include galvanizing, zinc plating, and phosphate coating, which provide additional corrosion resistance. Heat treatments can also be used to alter the mechanical properties, such as hardness and elasticity, to suit specific applications.

How to Choose the Right Belleville Spring
The best Belleville spring depends on more than diameter or material. Start with your required load, movement and working environment.
| Requirement | Recommended Belleville Spring Type |
|---|
| High axial force in limited installation space | Belleville Disc Springs |
| Higher load than one spring can provide | Parallel Disc Spring Stack |
| Greater total deflection | Series Disc Spring Stack |
| Higher load plus greater travel | Combined Disc Spring Stack |
| Corrosive or humid environment | Corrosion Resistant Disc Springs |
| Elevated operating temperature | High Temperature Disc Springs |
| Low-temperature or cryogenic service | Cryogenic Disc Springs |
| Bearing preload | Disc Springs for Ball Bearings |
| Valve preload or sealing force | Disc Springs for Valves |
For non-standard applications, the required load-deflection curve should be evaluated together with installation dimensions, operating temperature and expected service life.

Belleville Springs FAQ
What is a Belleville spring?
A Belleville spring is a conically shaped disc spring that deflects under axial compression. Its geometry allows it to generate relatively high force in a compact installation space.
Are Belleville springs and disc springs the same?
Belleville spring is commonly used as another name for a conical disc spring. However, Belleville washers used mainly for bolted joints may have a different design intent and applicable standard from precision DIN 2093 disc springs.
Can Belleville springs be stacked?
Yes. Belleville springs can be arranged in parallel, series or combined configurations. Parallel stacking increases load capacity, while series stacking increases total deflection.
Can Belleville springs be customized?
Yes. Custom options can include outside diameter, inside diameter, thickness, free height, load-deflection characteristics, material, surface treatment and stack configuration.
What should I provide when requesting a quotation?
A drawing is preferred. If a drawing is not available, provide OD, ID, thickness, free height, required load, deflection, operating temperature, material or corrosion requirement, expected operating cycles and quantity.
