1. Calculating the Required Force (Newton)

Gas spring force is measured in Newtons (N). To estimate the force required to lift a door or moving panel, you can use the following simplified formula:

F = (W × D / L) × 10

F (Force): Required gas spring force in Newtons

W (Weight): Weight of the door or moving component in kilograms

D (Center of Gravity Distance): Distance from the hinge to the door’s center of gravity

L (Installation Distance): Distance from the hinge to the gas spring mounting point

Professional Tip: Always add 10–15% to the final calculated value to compensate for the natural pressure loss that occurs over time.

2. Total Length and Stroke Length

Extended Length:

The distance between the center of the mounting holes at both ends of the gas spring when fully extended.

Stroke Length:

The portion of the shaft that moves inside the cylinder.

POWERTEC gas springs are manufactured in various lengths ranging from 15 cm to over 1 meter. Make sure the stroke length matches the opening angle of your door.

How to Identify Original POWERTEC Gas Springs from Counterfeit Products

To ensure safety standards, it is very important to purchase original products:

Laser Engraving:

Original POWERTEC gas springs feature laser‑engraved markings on the body, including the logo, traceable serial number, capacity (e.g., 250N), and safety warnings (Do Not Open – High Pressure).

Low-quality paper stickers are usually a sign of counterfeit products.

Shaft Quality:

The shaft in original models is completely polished, smooth, and coated with hard chrome.

Performance Test:

Original gas struts include a soft damping system near the end of the extension to prevent impact on hinges.

Fake models usually open quickly with a noticeable shock.

Frequently Asked Questions

1. What is a POWERTEC gas spring and how does it work?

A gas spring (gas strut) is a mechanical‑pneumatic component consisting of a cylinder filled with pressurized nitrogen gas and a shaft (rod).

The operation is based on the compression of nitrogen gas inside the cylinder. A small amount of oil inside the cylinder provides lubrication and also acts as a damping system near the end of the extension, ensuring smooth and shock‑free movement.

2. Where are POWERTEC gas springs used?

Due to their wide range of sizes and forces, POWERTEC products are used in many industries, including:

Automotive Industry:

Car hoods, trunk lids, and heavy vehicle side doors.

Furniture and Interior Design:

Cabinet doors (pump-type struts), folding beds (bed lift mechanisms).

Industrial Machinery:

Machine protective covers and inspection hatches.

Medical Equipment:

Hospital beds and dental chairs.

3. What do the numbers printed on a POWERTEC gas spring mean?

Several numbers and codes are printed on the body. The most important ones include:

Force Rating:

Indicated by N (Newton). For example 500N roughly corresponds to a load equivalent of about 50 kg.

Extended Length:

The total length of the gas spring from the center of the upper mounting hole to the center of the lower mounting hole (in millimeters).

Part Number:

Used for identification and reordering.

4. How do I know what gas spring force (Newton) I need?

Replacing an old unit:

The easiest method is to read the Newton rating printed on the existing gas spring.

New design:

You must calculate the door weight, opening angle, and the distance from the hinge to the mounting point.

As a general estimate, every 10N roughly equals about 1 kg of weight, but due to the lever principle, the gas spring force usually needs to be higher than the actual door weight.

5. What is the correct installation direction?

One of the most important installation rules:

The rod (thin shaft) must face downward and the cylinder must face upward.

Technical Reason:

This ensures the oil inside the cylinder remains in contact with the seal, lubricating it and preventing drying. It also allows the oil to act as a damping mechanism at the end of the opening movement.

6. Why can’t I compress my new gas spring by hand?

This is normal.

Gas springs rated above 100N or 150N are usually very difficult or impossible to compress by hand. They require the mechanical leverage of the door or lid to compress properly once installed.

7. Does the shaft require oil or grease?

No.

External lubrication attracts dust and particles. When the shaft retracts, these particles can damage the seal, causing gas leakage and early failure.

To clean the shaft, simply use a soft dry cloth or a slightly damp cloth with water.

8. Why has my gas spring lost its force?

Common causes include:

• Natural wear and aging of seals

• Scratched or damaged shaft

• Incorrect installation (e.g., upside down)

• Exposure to extremely high temperatures

9. Can a POWERTEC gas spring be repaired or recharged?

No.

Gas springs contain high‑pressure nitrogen gas (up to 150 bar) and are sealed units. Opening or attempting to recharge them is extremely dangerous and may cause serious injury.

Defective units must be fully replaced.

10. Does temperature affect gas spring performance?

Yes.

According to thermodynamic gas laws:

• Lower temperature → lower gas pressure (weaker performance)

• Higher temperature → higher gas pressure (stronger performance)

Typically, for every 10°C temperature change, the gas spring force changes by about 3–4%.

POWERTEC gas springs are designed to operate within a temperature range of:

−30°C to +80°C

11. What is the lifespan of gas springs?

Lifespan is measured by cycle count (opening and closing cycles).

A high‑quality gas spring, when installed correctly and used under standard conditions, can last 40,000 to 100,000 cycles, which is approximately 3 to 7 years of regular use.

Over time, about 1–2% of the gas inside the cylinder naturally leaks each year.
