Where it earns its place
Best-Fit Uses
Bolted-joint and bearing preload
Maintains clamping or contact as the joint settles, expands or changes slightly in service.
Valve, clutch and brake loading
Provides high axial force where available movement and height are both limited.
Holding preload in a short axial space
Useful where a compact annular part needs to maintain force despite small movement or settling.
Producing high force over short travel
Fits valves, clamps, bearings and release systems that cannot spare the height of a longer coil spring.
Why this style works here
What This Spring Style Solves
The conical disc shape stores high load in a compact annular envelope, and discs can be stacked to adjust combined travel and force.
Before you choose it
What to Confirm in Your Assembly
- Provide OD, ID, available height and load at the installed position.
- State required working travel and whether the stack will use series, parallel or mixed orientation.
- Provide inside diameter, outside diameter, installed height and the load at the working position.
- State whether discs are used singly or in a stack and how much total movement the stack must allow.
- Show the actual support and contact diameters because they influence how the disc is loaded.
Avoid forcing the wrong spring into the design
When Another Spring Style May Fit Better
Large disc stacks are affected by friction, alignment and contact surfaces. A simple ideal stack calculation should not replace review of the actual guide and assembly arrangement.
- Wave springs for lower load and more travel in low height
- Compression springs for longer strokes
- Rigid shims when compliance is not actually required
Keep material selection separate
Environment & Material Direction
For sustained preload, temperature and corrosion can affect long-term force retention. The Materials section covers those choices once the load path and available envelope are defined.
For the material families represented in this product's reference configurations, compare Carbon & Alloy Spring Steels. Confirm the exact grade and condition for your assembly.

Application questions
Frequently Asked Questions
What changes when Belleville discs are stacked in series or parallel?
Series arrangements generally add travel, while parallel arrangements generally add load capacity. Mixed stacks can combine both, but friction and guidance also influence the real response.
Can disc springs be stacked to change load or travel?
Yes. Series and parallel arrangements can change the combined response, but stack friction, guidance and contact surfaces also influence the real result and should be included in the assembly review.
What should I send for an application review?
Send the assembly drawing or a clear sketch, the working positions, the force or torque you need, expected cycles, environment and quantity. If an existing spring is being replaced, include its dimensions and explain what is not working well in the current design.
