Double rod symmetrical gas spring. This is the latest product developed by our factory. It is mainly used for opening and closing the top cover of automobiles, ships and airplanes. This kind of gas spring has a cylinder in the middle and a piston rod at both ends. It can be compressed by two rods at the same time or by a single rod. Because of its good damping force and no noise, it is the best product to replace the current mechanical shutter. We also can make it as auto lock type gas spring, when we push the rod inside the cylinder, the rod will auto lock by itself, and we push the rod again, the rod will auto extend outside from the cylinder by itself.

No.1 Features and Application

Bidirectional Support Gas Springs are often used in the fields of vehicles, aircrafts, and fitness equipments. Our products can eliminate the noises and have the damping effect.

No.2 Buying Guide

According to the different designs, we support two models for you to select.

(1)Two piston rods are compressed in the same time. In this way, the piston rods and strengths about two rods are equal, and only having one extension force.

(2)Two piston rods are compressed in sequence. This design is more complicated. The piston rods and strengths about two rods can be selected with unequal parameters. Specifically, you may choose the parameters according to the following picture.

 

d1: left rod diameter d2: right rod diameter: tube diameter

S1: left stroke S2: right stroke L: extended length

F1: left extension force F2: right extension force

 

In this model, you have some more choices:

d1< or >or = d2 ,

S1or= S2 ,

F1 or = F2
