Stainless Steel Belleville washers, also known as conical spring washers or disc springs, are versatile mechanical components commonly used in various applications to provide spring-like behavior for managing loads and maintaining tension. They are characterized by their conical shape, which allows them to absorb and distribute loads in a controlled and predictable manner. Here are some key features and common applications of Stainless Steel Belleville washers:

Features of Stainless Steel Belleville Washers:

  • Material: Stainless Steel Belleville washers are made from stainless steel, which offers various grades and alloys to choose from, depending on the specific requirements of the application.
  • Corrosion Resistance: Stainless steel provides excellent resistance to corrosion and rust, making it suitable for applications where exposure to moisture and other corrosive elements is a concern.
  • High Strength: Stainless Steel Belleville washers can withstand significant loads and provide reliable spring action while maintaining their structural integrity.
  • Predictable Spring Rate: These washers offer a consistent spring rate, which means their load-deflection characteristics are well-understood and can be relied upon for precision applications.
  • Wide Temperature Range: Stainless Steel Belleville washers can operate effectively over a wide temperature range, making them suitable for both high and low-temperature applications.

Applications of Stainless Steel Belleville Washers:


Stainless Steel Belleville washers find applications in a wide range of industries and applications, including:

  • Bolted Joints: They are used in conjunction with bolts and nuts to maintain proper tension and prevent self-loosening in critical bolted joints, such as those in machinery, aerospace, and automotive applications.
  • Valves and Pumps: In the fluid control industry, Belleville washers are used to maintain a consistent load on valve packing and gaskets, ensuring effective sealing.
  • Spring Preload: They are often used to provide consistent spring preload in various mechanical assemblies, including clutches, brakes, and bearing systems.
  • Pressure Relief Devices: Belleville washers are employed in safety pressure relief valves and devices to control and manage overpressure conditions.
  • Electrical Contacts: They can be found in electrical contact assemblies to maintain proper contact pressure and ensure electrical conductivity.
  • Vibration Damping: In applications where vibration isolation is required, Belleville washers can help absorb and dampen vibrations, reducing the risk of fatigue and component failure.


Stainless Steel Belleville washers are available in different sizes and thicknesses to accommodate various load and deflection requirements. When selecting these washers for a specific application, it's crucial to consider factors such as the required load capacity, deflection, temperature range, and corrosion resistance.
