Do you know the different installation between gas strut and damper?


Rod Down or Rod up? Are you uncertain about the installation method for the gas shocks? Don’t worry, we’ll walk you through the correct installation process for different types of gas springs step by step in this article.

Gas Spring Classification

To begin, let’s classify the gas springs into two categories: lift support gas struts and dampers. In flip-up cabinets, we typically utilize lift support gas struts. These are designed to effortlessly lift the cabinet door and hold it open, allowing for easy access to your belongings and freeing up your hands.

Compared to lift support shocks, dampers are less commonly used but serve important functions. Dampers come in two main types: extension dampers and compression dampers. Extension dampers regulate the speed of cabinet door opening, making them ideal for applications like hidden drop shelves. Conversely, compression dampers are designed to slow down the closing speed of box doors, preventing slam shut and potential accidents, particularly for children. This is why they’re often referred to as soft-close gas springs or slow-close hinges.

Correct Installation

Once you’ve grasped the variances among different gas springs, selecting the suitable installation method becomes straightforward. We’ll also explain why this method is essential.

Firstly, for lift support gas struts, it’s best to install the metal rod facing downwards. Opt for a more vertical installation for heavier lids, and a slightly tilted horizontal approach for lighter ones. Regardless of weight, the rod should always face downwards. This orientation ensures constant lubrication of the seal, extending its lifespan. Moreover, with the rod facing downwards, lubricating oil accumulates at the cylinder’s bottom. As the gas struts near closure, this accumulated oil acts as a damper, slowing down the lid’s descent and preventing slamming.

Secondly, the installation direction for dampers depends on the damper type. For extension dampers, install the metal rod facing downwards. For compression dampers, it must face upwards. This consistent orientation ensures uniform damping throughout the entire stroke. Incorrect installation may weaken or negate damping effects. Here, you don’t need to concern about lubricating the seal for dampers, because the principle of the damper is to fill it with oil to provide resistance. Therefore, they contain ample oil inside, eliminating lubrication worries.


In conclusion, we have illustrated the relationship between different gas struts and their installation methods through a diagram. If you’re in need of lift support gas struts or gas spring dampers for your projects, take the next step and start your shopping journey with us today.
