The Auto BLOCK type of gas spring is versatile in its applications. This is because it can be locked in any intermediate position. Think of the reclining back rest of a seat in a luxury bus. The back rest can be adjusted to the passenger’s comfort angle because of the gas spring.

In this Auto LIFT type, damping is provided during opening / extension of the gas spring. Just before the gas spring completely extends, the speed of opening slows to avoid impact at the end. This is the most commonly used type of gas spring where ever a simple opening of lids, doors, luggage compartments, etc. is needed.

Damping in Compression
In this type, damping is provided during closing / compression of the gas spring. The damping is provided to avoid impact during closing of the application. For example, to avoid slamming of a door on the door frame while it is closing. In this type, the closing effort required near the compressed condition is more due to damping provided.

Both Side Damping
This is a combination gas spring of the first two types, i.e. Damping in Extension & Damping in Compression. The applications of this type are unique, e.g., opening and closing of doors in highly windy conditions at high altitudes, where damping is required simply to oppose the wind force in either direction, while opening or closing.

End Position Lock is a safety feature where in, at completely extended position, a mechanical stopper automatically locks the gas spring from compressing. To compress, the mechanical stopper has to be unlocked manually. This feature is usually recommended on applications where hoods have to be held in open condition in a vibrating structure. E.g., on the engine hoods of earth moving machines.

Electric Auto Lift
This is a unique gas spring which conducts electricity if fitted in a circuit. E.g., it can be fitted on Tailgate / boot of a vehicle where the closing of the boot door is motorised and the opening is done by the gas spring.
