Damping

ARITECH Gas Springs are filled with a defined amount of oil for lubrication of the seal package and for smooth end position damping in the final position of the gas spring on your application. Without damping, rapid extension could cause possible product failure associated damage injury Uncomfortable final positioning of the gas spring application. The damping performance of a ARITECH Gas Spring can be determined individually to customer requirements by way of linear, progressive or regressive spring characteristics.

Linear Damping

• Hydraulic damping in push-out direction
• Dynamic damping
• in push-out direction
• in push-in direction
• in both directions

All gas springs are supplied with a defined linear damping length in push out direction as either hydraulic damping or dynamic damping. Standard gas springs are equipped with hydraulic damping which is achieved by a piston nozzle (transfer chamber). The standard hydraulic stroke length (damping length) for push-out damping of a Lift is chosen to ensure comfortable damping, suitable for most applications, and for a comfortable progression of the gas spring. The hydraulic damping can only be utilized when the gas spring is installed with the piston rod downwards.

The dynamic damping is achieved by a groove inside the tube of the gas spring. The extension speed and the damping range of the gas spring can be adjusted by the geometry and length of the groove. Contrary to hydraulic damping, dynamic damping can be utilized while the gas spring is mounted in any desired position.

Additionally, a linear damping in push-in direction or damping in both directions is available on request. If you believe that you will need a special linear damping, either in push-out, push-in or in both directions, please contact our sales department for assistance.

In some applications, a stroke controlled force supply is required instead of linear damping. For such applications we offer you our Lift type gas spring with progressive or with regressive damping. While the linear damping feature is achieved through oil; progressive and regressive damping features are achieved through an internal coil spring.

Progressive Damping

This type of damping is suitable where a particularly high extension force in the push-in direction of the gas spring is needed. The force and the damping length can be determined individually .

Regressive Damping

This damping solution is suitable where a high extension force in the push-out direction is needed. Also on this damping feature the force and the damping length can vary according to customer requirements. On request, a combination of both, progressive and regressive damping, is also available.

Speed

Gas springs are speed control devices. On some occasions they are used to reduce or to increase the speed of your application. When ordering a ARITECH Gas Spring without mentioning your special speed requirement, it will be furnished according to our standard.

On request we can produce the gas spring according to your requirement. They can be either slow or fast. Please contact our sales department for your special speed requirements (Please note that the pneumatic speed is measured when piston rod is downwards)
