Manufacturers and Suppliers of Disc Spring Washer

A disc spring washer, also known as a Belleville washer or conical spring washer, is a type of spring shaped like a washer or disc with a conical shape. This design allows the washer to provide a preload between a fastener and the substrate, ensuring that the fastener remains tight despite vibration, thermal expansion, or contraction.

Key Features and Uses

Spring Action: The conical shape provides a spring-like force when compressed, ensuring a constant load and maintaining tension in bolted joints.
Load Distribution: Disc spring washers help distribute the load evenly, reducing the risk of damage to the substrate or the fastener.
Space Efficiency: Due to their compact size, they are suitable for applications where space is limited.
Customization: They can be designed to specific load and deflection requirements by adjusting the material thickness, diameter, and cone height.

Applications

Automotive Industry: Used in clutches, brakes, and other assemblies where maintaining tension is crucial.
Aerospace: Ensures reliability in high-vibration environments.
Electrical Equipment: Maintains consistent contact pressure in connectors and assemblies.
Industrial Machinery: Provides reliable tensioning in heavy-duty applications.
Selection Criteria
Material: Common materials include spring steel, stainless steel, and other alloys, chosen based on the operating environment (e.g., corrosion resistance, temperature tolerance).
Dimensions: Inner and outer diameters, material thickness, and cone height are selected based on the load requirements.
Load and Deflection: The washer must be chosen to provide the correct load and deflection characteristics for the application.

Installation Tips

Proper Orientation: Ensure the washer is installed with the convex side facing the nut or the element providing the load.
Stacking: For higher loads or greater deflections, multiple washers can be stacked in parallel or series configurations.
Lubrication: In high-friction applications, lubrication can reduce wear and enhance performance.

Advantages of Disc Spring Washer
