Spring Design

Design information for engineers, such as spring calculation formulas,

which are the basis of spring design, can be found here.

Flat Spiral

When design, the load characteristics differ depending on the type of flat spiral spring, and so it is necessary to select and examine the load characteristics according to the application.

Typical types of stress are non-contact type, contact type, and constant load type.
The load characteristics of each are shown below.

For the spring stress, there are cases where the yield point of the material is applied, but it is recommended to consider the safety factor according to usage and shape of the spring.

Based on our vast experience, we will make proposals to you with an appropriate spring stress.
