Key Considerations for Belleville Fasteners

When selecting or buying Belleville washers (often referred to as Belleville springs or disc springs), there are several key considerations to keep in mind:

  1. Material: The material of the Belleville washer should be chosen based on the specific application requirements such as temperature, corrosion resistance, and load capacity. Common materials include steel, stainless steel, and inconel.

  2. Size and Dimensions: The size and dimensions of the Belleville washer need to match the design requirements, including the outer diameter, inner diameter, and thickness.

  3. Load Capacity: Ensure that the Belleville washer can handle the expected load and provide the required amount of force or deflection without permanent deformation.

  4. Fatigue Life: Consider the number of cycles the Belleville washer needs to endure and select a washer with a suitable fatigue life to prevent failure over time.

  5. Stacking Configuration: Belleville washers can be stacked in series or parallel configurations to achieve different load/deflection characteristics. Understand the desired stacking configuration for your application.

  6. Surface Finish: The surface finish of the Belleville washer can impact its performance, so select a washer with the appropriate finish for your application.

  7. Supplier Reputation: Choose a reputable supplier or manufacturer known for producing high-quality Belleville washers to ensure product reliability and performance.

By considering these factors, you can select the appropriate Belleville washers for your specific application needs.
