What is an M-strut spring?
 

An M-Strut resembles a conventional compression gas spring. From its appearance, you cannot tell the difference, but inside the gas and gaskets have been replaced by an ordinary wire compression spring.

Description

The wire spring gives M-Struts a regular linear force curve - in contrast to the flatter force curve of conventional gas springs.

As M-Struts has no oil in the cylinder, it is not dampened in the last portion of its full extension.

Fitting And Use

M-Struts is used instead of gas springs in structures subject to impacts and vibrations. M-Struts may be used to great advantage in dirty and dusty environments, where a gas spring would suffer leakage due to its surroundings.

M-Struts is a good choice in structures where its function is used only rarely - such as emergency exits. M-Struts can cope with being subjected to loads over a prolonged period without being moved.

M-Struts must not be used as a stop, but should be incorporated so that it is controlled and limited by the movement of the structure.

Our large range of End Fittings can also be used on M-Struts - and provide great flexibility in installation.

Service life of springs

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.

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