Where it earns its place
Best-Fit Uses
Clutch and release interfaces
Transfers axial force through defined fingers or contact rings around a central opening.
Custom contact and preload parts
Combines a compact disc envelope with local flexibility or selected contact regions.
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
Slots and contact features change where the disc flexes and how force reaches the mating component, which is useful for release systems, specialized contacts and custom preload layouts.
Before you choose it
What to Confirm in Your Assembly
- Provide the actual support and contact diameters rather than only OD and ID.
- Show slot, finger and cutout geometry and state force at the real contact points.
- 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
Changing slot length, contact diameter or support position can change the response significantly. Those features are working geometry, not cosmetic details.
- DIN 2093 Belleville discs for simpler preload
- Diaphragm springs for fingered annular release action
- Flat springs when a central opening is unnecessary
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.

Application questions
Frequently Asked Questions
Why use slots in a disc spring?
Slots can move the flexible region and control how force reaches the mating part. They are useful when a plain conical disc cannot provide the required contact or release geometry.
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.
