Compression Springs - Stainless Steel

Technical drawing - Compression spring - Range ABC
A compression spring is used in a large number of structures where compressed force is required. The force accumulates when the spring is being compressed, and the force is released again when the spring is allowed to return to its original length. A compression spring is basically an ingenious low-tech component that can accumulate force and operate at optimal levels for a long time, provided it is used and dimensioned correctly. Please note that stainless steel springs are generally 10% weaker than the corresponding springs in piano wire. See below our large selection of different sizes. Most of them in stock, ready for dispatch!

Material

DIN 17224 AISI 302 WERKSTOFF NO. 1.4310
Working temperature between -200 ºC and +250 ºC
Produced in stainless steel for use in all environments.

Tolerances

Range A: (The A Range consists of springs with 5 digits, ie: "12200")

IN 2098 defines the spring's dimensions based on wire thickness. Contact Sodemann-Springs.US for further information.

DIN 2095 defines the force as the determining parameter. The number of coils may therefore vary. L0 is for guidance only and may well be longer than stated in the tables. Deviations are usually observed in a large coil ratio (Dm/d), where the spring has a thin wire in relation to the diameter. Once loaded the spring will set itself and thus achieve the correct force at the correct travel. Contact Sodemann-Springs.US for further information.

Range B: (The B Range consists of springs with 11 digits and 2 letters, ie: "C07200853000M")

On this range, the number of coils is not shown, because the spring is produced after the force as the primary measurement. Therefore the variation in wire size, through tolerance or availability, will always have an effect on the number of coils.

Calculation of spring force

Fn for stainless steel spring steel is approx. 0.88 x Fn for music wire.

Calculation of spring force at a given length is travel s * R

For example:
A spring is compressed 16 mm and the spring constant is 3 N (16 mm * 3 N = 48 N)
A spring that travels 16 mm thus produces 48 N, which equates to approx. 4.8 kg.

If compression springs with a very high spring constant/carrying capacity are required, coloured die springs are recommended.

Configuration of ends

Range A: Wire up to and including 0.8 mm is closed, but unground. Wire from 1.0 mm is closed and ground.

Range B: Outside diameter up to and including 2,24 mm is closed, but unground. Outside diameter from 3,05 mm is closed and ground

Winding direction

Normally right-handed

Misc.

If the springs are compressed to Ln, the spring will set itself. It will then not return to its original length, L0.

Always dimension a spring so that it delivers the desired travel and force with as little exertion as possible. This prolongs the service life of the spring. Applying maximum load to the spring will shorten its service life and cause it to become permanently distorted.
