Read the catalogue dimensions

The catalogue lists each disc spring by article number and ordering dimensions: outside diameter De, inside diameter Di, thickness t, t′, free height l0 and cone height h0. The rows shown are standard-material springs in the catalogue’s 6–15 mm De section and are assigned DIN EN 16983 group 1.

Use the article number to stay with the exact catalogue row. Do not estimate a missing size by interpolation: spring series and geometry affect load, travel and stability.

Understand the force test point

The published force F is measured at spring travel s = 0.75 h0. The listed test length lT corresponds to that same point. These fields describe a catalogue test condition; they are not a universal rated load or fatigue-life value.

For example, article 001 400 B has De 10 mm, Di 5.2 mm, t 0.40 mm and a stated force of 209 N at the catalogue test point. Other springs with the same outer diameter can have different inner diameters, thicknesses and force.

Check stack and operating conditions

A disc spring stack changes its force and travel according to how the springs are arranged. Friction, guidance, tolerances, preload, material and cycle duty also influence performance. Use the manufacturer’s current technical manual and the exact spring series for stack calculations.

This dimensional lookup does not establish fatigue life, allowable stress, corrosion suitability or a safe assembly load. Confirm current availability and tolerances with the manufacturer before specifying a spring.

Keep dimensions tied to the article number

The ordering dimensions include both t and t′; these are separate catalogue fields and should not be collapsed into one thickness value. The manufacturer also lists l0 and h0 separately. Use the catalogue sketch and the exact article number to identify how each dimension is measured.

The catalogue rows include spring travel, test force, test length, weight and pack quantity where shown. A dash for packing means the brochure gives no pack count for that row; it is not a zero quantity.

Select by the full geometry

A De of 10 mm does not identify one unique spring. The table includes several 10 mm variants with different Di and thickness values, and their force at the same relative test point varies substantially. Select by the full dimensions and article number, then check the part drawing.

Free height l0 and cone height h0 describe different geometric measures. Confirm their definitions in the catalogue drawing before setting an installed length or preload; do not treat the spring’s free height as its working height.

Use the series limits

This excerpt covers selected small standard-material springs only. Disc springs are available in other materials, dimensions and series, and their force curves need not match these examples. Use a current datasheet for the exact product supplied.

For a critical application, also review tolerance class, surface protection, temperature, fatigue cycle count, lubrication and stacking guidance. The brief table gives catalogue comparisons; it does not replace manufacturer calculation or qualification.

Treat force as a catalogue point

A catalogue force at 0.75 h0 is one defined point on a nonlinear load-deflection curve. It does not mean the spring should be continuously compressed to that travel in every application. Confirm the operating range and permissible stress for the selected series.

The listed weight and packing quantities are purchasing details, not spring-performance values. Keep dimensional, load and logistics fields separate when comparing products or building a bill of materials.
