When it comes to selecting the right gas struts for your project, the process might seem straightforward at first, but there are several important factors to consider. Whether you’re working on a vehicle, cabinetry, or an industrial application, choosing the perfect gas struts ensures efficiency, safety, and durability. Gas struts Australia play a critical role in enabling smooth opening and closing motions in various mechanical structures. They are widely used in applications like doors, hatches, lids, and more. Getting the right one can make all the difference between a project that functions seamlessly and one that falters.
Here’s a comprehensive guide with top tips for choosing the perfect gas struts for your specific project.
Know What You Need For Your Project.
The first step in selecting gas struts is understanding the requirements of your project. This involves knowing the weight of the object you need to support and move, as well as the desired motion. Gas struts come in a range of sizes, force ratings, and damping characteristics, so being clear about your project’s functional requirements helps narrow down the choices.
- Weight Support: Determine the weight of the lid, door, or object that the gas struts will support. The force of the gas strut should be sufficient to lift and hold the object in place but not so strong that it makes it difficult to close.
- Movement Angle: Gas struts allow varying degrees of movement. Some applications require a full opening (like a car trunk), while others only need partial movement.
- Speed Of Motion: Different gas struts provide different speeds for opening or closing. For example, slow and controlled movement might be preferred in kitchen cabinets, while faster action could be needed for industrial equipment.
Choose The Correct Force Rating
Gas struts are available in various force ratings, typically measured in Newtons (N). The force rating you need will depend on the weight of the object being lifted or supported. To calculate the required force rating:
- Divide the weight of the object by the number of gas struts you’ll use.
- Consider the length and pivot point to ensure proper force application.
For example, if you are using two gas struts to lift a 10 kg object, you would divide the object’s weight by two and convert it to Newtons (1 kg equals approximately 10 Newtons). In this case, each strut should be rated for 50 Newtons to provide the necessary support. Picking the correct gas strut force will make sure it works smoothly and keep the strut and its connected parts from wearing out.
Consider The Mounting Position
The mounting position of gas struts can significantly affect their performance and longevity. Proper mounting ensures that the gas struts work efficiently and maintain stability throughout their use. When installing gas struts:
- Upper Mounting: Attach the body of the strut to the stable part of the structure (like a frame) and the rod to the moving part (like a lid or door).
- Correct Angle: Gas struts should generally be mounted at a slight angle, ensuring that the gas pressure lubricates the seal and reduces friction, improving the strut’s life span.
- Mounting Brackets: Ensure that the mounting brackets you use are strong enough to handle the force and weight load.
The positioning also affects how the struts handle the load distribution and the angle at which the door or lid opens.
Choose The Right Type Of Gas Strut
Gas struts come in different types depending on your needs, such as:
- Standard Compression Gas Struts: These are the most common and are used for lifting and holding applications. They compress when force is applied.
- Lockable Gas Struts: These are ideal for situations where you need the strut to lock in place at any point, providing added stability.
- Tension Gas Struts: These work in the opposite direction of standard struts by pulling rather than pushing, making them suitable for applications like tensioned furniture or gym equipment.
- Stainless Steel Gas Struts: Perfect for marine or outdoor use due to their corrosion resistance.
Choosing the right type of gas strut ensures that your project can withstand the environmental conditions and stresses it may encounter.
Pay Attention To The Material And Finish
Gas struts need to be made of the right material and have the right finish if they are going to be in harsh settings, wet conditions, or chemicals. Common materials include steel, stainless steel, and aluminium.
- Steel: Suitable for indoor applications where moisture exposure is minimal.
- Stainless Steel: Ideal for outdoor or marine environments where corrosion resistance is critical.
- Protective Coating: Many gas struts come with coatings to further protect against rust, UV radiation, or chemicals, so be sure to select one with appropriate protection for your project.
Select The Right Damping And Valve Features
Damping is another factor to consider when selecting gas struts. Damping allows for the smooth, controlled opening or closing of a lid or door, preventing sudden movements that can cause damage. Some gas struts offer adjustable damping, allowing you to fine-tune the operation to match your requirements.
Additionally, some advanced gas struts come with integrated valves that can regulate speed and force, making them suitable for projects that demand precise control over movement.
Test Before Final Installation
Before permanently installing the gas struts in your project, it’s always a good idea to test their performance in situ. Ensure they are easy to install, open and close smoothly, and provide adequate support. Testing will help you make any necessary adjustments to force, positioning, or angle, ensuring a perfect fit.
Conclusion
Selecting the right gas struts can elevate the performance and longevity of your project. By understanding the load requirements, mounting considerations, material properties, and additional features such as damping and valve control, you can ensure that your gas struts will provide the smooth and reliable motion that your project needs. Taking the time to carefully choose and install the correct gas struts will result in a successful, long-lasting solution.
