Belleville Springs

Belleville springs are curved disc springs used when a compact component needs to provide spring-like action and controlled compression in heavy-load applications. They are commonly selected for fastening, hardware, maintenance, assembly, replacement, and equipment service work where outside diameter, inside diameter, material, and pack quantity must fit the assembly.

Use Cases

Support compact spring action

Use Belleville springs in heavy-load fastening, hardware, assembly, maintenance, replacement, and equipment service applications that call for a compact disc-shaped spring component.

How to Choose

Match the spring to the assembly

Start with the required outside diameter and, where listed, inside diameter. Then compare the specified material and choose a pack quantity that suits the planned installation or replacement task.

Applications

Built around controlled compression

The curved disc profile is used where spring-like action and controlled compression are needed within an assembly, including applications with limited space for a compact spring element.

Planning Guide

Plan the right fit before choosing

Understand the design

Why choose a Belleville disc spring?

Belleville springs have a curved disc profile rather than the form of a conventional coil spring. This shape provides spring-like operation in a compact component and is represented here for heavy-load applications.

  • Curved disc form provides spring-like action.
  • Compact shape suits fastening and hardware assemblies.
  • Used where controlled compression is needed.
  • Available in stainless steel and carbon steel constructions.
Plan for fit

Check both outside and inside diameter

Diameter is a central selection point. Compare the listed outside diameter with the available assembly space, and use the inside diameter where provided to assess compatibility with the applicable fastener or assembly requirement.

  • Available outside diameters include 0.343 in., 0.75 in., 1.125 in., 1.5 in., 2 in., and 2-1/2 in.
  • Listed inside diameters range from 0.164 in. to 1-1/4 in.
  • Some 0.75 in. OD options have different listed inside diameters.
  • Confirm the dimensions required before selecting a pack.
Choose material and quantity

Select the represented construction and pack size

Choose between 302 stainless steel and carbon steel options according to the component requirements stated for your application. Several carbon steel products specify 1074 carbon steel. Pack quantities are offered in six-piece and 12-piece options for installation or replacement needs.

  • 302 stainless steel options are available in several outside diameters.
  • Carbon steel options include products specified as 1074 carbon steel.
  • Six-piece packs are represented in select sizes.
  • Twelve-piece packs are represented across multiple sizes.
