Spring Assortments for Prototyping, Development and Repairs
Spring assortments contain a selection of different compression springs, extension springs or both spring types in a clearly organised storage box. They are particularly suitable for product development, prototyping, maintenance, workshops and training where various dimensions need to be available for immediate comparison and testing.
Instead of defining one specific spring in advance, different sizes can be tested directly in the application. The springs are sorted by dimension and suitable versions can later be reordered as individual standard parts.

How to Select the Correct Spring Assortment
First select the required spring type. Compression springs absorb compressive forces and are shortened during use. Extension springs operate under tensile load and have attachment loops. Mixed assortments are useful where both operating principles are regularly required.
Next, compare the number of sizes, total quantity and wire diameter range. An assortment containing many sizes provides a wider choice. A larger total quantity normally includes several springs of each dimension and is particularly practical for repeated testing or minor repairs.
Spring steel 1.1200 is suitable for many general applications in dry environments. Stainless spring steel 1.4310 provides improved corrosion resistance and is often the better choice for humid or regularly cleaned areas. Suitability for salts, acids or aggressive cleaning agents must be assessed separately.
Recommendations for Use
Springs from an assortment should be measured and tested under actual operating conditions before installation. Outside diameter, length and wire diameter alone are not sufficient to determine the spring force and permissible travel reliably.
The springs must not be compressed or extended beyond their permissible working range. For series production, safety-related assemblies or precisely defined spring forces, a clearly specified individual spring should be selected after testing.
Suitable standard versions can be found in our compression springs and extension springs ranges.
Frequently Asked Questions About Spring Assortments
Are all springs in an assortment identical?
No. Each assortment contains several dimensions and normally multiple springs of each size.
Can individual springs be reordered?
Yes. Suitable standard springs can be selected and ordered separately using their dimensions.
Are spring assortments suitable for series production?
They are mainly intended for selection, testing, repairs and prototyping. A clearly defined spring should subsequently be used for series applications.
