Gas Spring Lifetime
Here at European Springs we cater to designing and manufacturing springs which can be used day in day out, never losing standard of force. The gas springs we produce generally permit to have a maximum force loss of 10% after 40000 cycles at a max of five cycles per minute at room temperature in ideal fitting circumstances.
However, it must be remembered that gas springs have a shelf life as the sealing material ages and wears out, though we do try our best to prolong this as much as possible through various technological methods.
There are several factors that affect gas spring lifespan in an application; external factors such as temperature changes as well as other physical environmental influences can affect seal aging and wear, thereby speeding up the process of force loss.
In addition, fitting also plays a significant role. If, for a majority of its operational life, a gas spring has its piston rod pointing downwards, the seals and the piston rod will be kept lubricated with oil, thus minimising wear and leakage and massively elongating their lifetime of use.
We also urge our clients to acknowledge that a gas spring will last longer if it is installed free from vibration where lateral forces can be produced. This is why our expert design team always choose gas springs with the largest possible cylinder volume for the amount of force required in order to give optimum performance for the specific application.
