Disc spring stack calculator
Find a disc spring stack in parallel and series arrangement from your operating point, or calculate a stack of your own.
Calculated to EN 16983 and scaled to the catalogue force at L1. Friction and guide clearance are not included. Real forces vary with tolerances, so test the installation before series use.
Not sure, or need something special?
Send us your installation space and forces and we help you choose the right stack.
Link parameters for engineers, ERP and AI assistants
Every input can be set in the web address, so a link opens the exact result. Use it to save a search, send it to a colleague or let an AI assistant find a disc spring stack for you.

- Calculate a stack: Stack length L cL (mm)
- De, Di
- Outer diameter. Needs clearance to the bore. Inner diameter. Needs clearance to the guide pin.
- t
- Thickness of the disc.
- l₀, h₀
- Height of one unloaded disc. Travel to flat: h0 = l0 − t.
- Parallel
- Discs nested in the same direction. More force, same travel.
- Series
- Packets turned alternately. More travel, same force.
- L, F
- Height of the whole stack. The force F is given at this height.
Replacing a stack? Count the discs and note how they face each other, then measure De, Di and t with a calliper. Not sure? Send us a photo.
