The ends have been finished without grinding.

Usually right. The force and application is not affected by the direction of wind.: Standard conical compression springs are not defined with a specific direction of wind. Depending on production, the springs may be either right or left wound.

The service life of a spring is generally very difficult to define. A large number of parameters come into play, and it is therefore impossible to define a service life.

Parameters with a significant influence on service life include:

Installation, installation method, number of movements, vibrations, shocks, torsion, length of travel, non-axial travel, temperature, wear against other surfaces, environment of use, any cleaning agents, lateral impacts, etc.

Always dimension a conical compression spring so that it delivers the desired travel and force with as little exertion as possible. This will give the spring the longest possible service life.

Applying the maximum load to the spring or exceeding it will shorten its service life and may cause it to become permanently distorted.

Therefore we recommend that you do not use more than 75% of the maximum travel (Sn) of conical springs.

Conical compression springs will more or less set themselves depending on the load and travel.

Conical compression springs can deliver travel down to a height (Ln) of approximately 2 x the wire thickness (d). However, this is not recommended due to reduced service life.

If a conical compression spring is compressed to its maximum loaded length (Ln), the spring will permanently set itself. It will then not return to its original length (L0).
