Extension Springs - Spring Steel / Music Wire

Technical drawing - Extension spring - Range D

This series is available in three different lengths: 300mm, 500mm and 1,000mm. These springs are mainly used for testing – you can cut the springs to the desired length and then create loops. The springs are also available in stainless steel wire.

Please note that these springs do not have loops.

Material

DIN 17223 C-Wire WERKSTOFF NO. 1.200
Working temperature between -30 ºC and +120 ºC
Produced in spring steel for use in dry environment. The spring steel is not rust-resistant. If needed for use in humid/wet environment, choose from our collection of models in stainless steel here.

Loops

These springs comes with no loops.

Spring constant

There are no spring constants for this range of springs. These springs are designed to test and try where the springs can be shortened to achieve the desired length. The spring constant depends on the length, so we are unable to provide a general spring constant.

Winding direction

Normally right-handed

Standard springs are not defined with a specific direction of wind. Depending on production, the springs may be produced either right or left wound. If you require a specific direction of wind a special spring must be produced.

Misc.

The springs are intended for tests and experiments. You can cut them to the required length.

If an extension spring with an exact value for one of the following parameters is required, springs must be custom-made:
- Loop type
- Loop height (LH)
- Loop position (X)
- Loop width (if the spring is to be incorporated into a tube)
- Opening at loop (m)
- Initial force (F0)
