Hey there! As a supplier of Bonnet Gas Struts, I often get asked how to match the right size of these struts to a vehicle. It's a crucial question because getting the wrong size can lead to all sorts of problems, from a bonnet that won't stay open to one that's too difficult to lift. So, in this blog, I'm gonna walk you through the process step by step.
Understanding Bonnet Gas Struts
First things first, let's talk a bit about what Bonnet Gas Struts are. These are hydraulic or gas - filled cylinders that help in lifting and holding the bonnet of a vehicle in an open position. They work by using compressed gas to provide a smooth and controlled movement. You can check out more about Bonnet Gas Spring on our website.
Factors to Consider When Choosing the Size
1. Vehicle Make and Model
The make and model of your vehicle are the most important starting points. Different cars have different bonnet weights, sizes, and opening mechanisms. For example, a small compact car will have a much lighter bonnet compared to a large SUV. You can usually find the recommended gas strut size in your vehicle's owner's manual. If you don't have the manual, you can also check online forums or contact the vehicle manufacturer.
2. Bonnet Weight
The weight of the bonnet is a key factor. Heavier bonnets require gas struts with a higher force rating. To measure the weight of the bonnet, you can use a luggage scale. Just attach the scale to the front edge of the bonnet and lift it slightly to get a reading. Make sure to take the measurement when the bonnet is in the fully closed position.
3. Bonnet Length and Width
The dimensions of the bonnet also play a role. Longer and wider bonnets may need longer gas struts to ensure proper support and movement. Measure the length from the hinge point to the front edge of the bonnet and the width at the widest point. This information will help you choose the right length of the gas strut.
4. Opening Angle
The opening angle of the bonnet is another consideration. Some vehicles have bonnets that open at a steep angle, while others have a more gradual opening. Gas struts need to be able to support the bonnet throughout its entire opening range. You can measure the opening angle using a protractor or an angle - measuring app on your smartphone.
Measuring for the Right Size
Step 1: Measure the Mounting Points
Locate the mounting points on the vehicle where the gas struts are attached. Measure the distance between the center of the mounting holes. This will give you the "mounting center distance" which is an important dimension for choosing the right gas strut.
Step 2: Measure the Extended and Compressed Lengths
Open the bonnet fully and measure the distance between the mounting points. This is the extended length of the gas strut. Then, close the bonnet and measure the distance again. This is the compressed length. Make sure to measure accurately, as even a small error can affect the performance of the gas strut.
Matching the Force Rating
Once you have all the measurements, it's time to match the force rating of the gas strut. The force rating is usually measured in Newtons (N) or pounds - force (lbf). As a general rule of thumb, you want a gas strut with a force rating that is slightly higher than the weight of the bonnet. This ensures that the bonnet can be lifted easily and held securely in the open position.
For example, if your bonnet weighs 20 kg (about 44 lbs), you might want to choose a gas strut with a force rating of around 250 - 300 N (about 56 - 67 lbf). However, this is just a rough estimate, and you should always refer to the manufacturer's recommendations.
Other Types of Gas Springs
We also offer other types of gas springs, such as Murphy Bed Gas Spring and Gas Lift for Furniture. These gas springs work on similar principles but are designed for different applications.
Installation Tips
Installing Bonnet Gas Struts is usually a straightforward process, but it's important to follow the correct steps. Make sure to wear safety glasses and gloves. Start by removing the old gas struts if you're replacing them. Then, attach the new gas struts to the mounting points on the vehicle and the bonnet. Make sure the struts are properly aligned and tightened.
Common Mistakes to Avoid
- Choosing the Wrong Size: As mentioned earlier, getting the wrong size can lead to poor performance. Always double - check your measurements and consult the manufacturer's recommendations.
- Improper Installation: Incorrect installation can cause the gas struts to fail prematurely or not work at all. Follow the installation instructions carefully.
- Ignoring Safety Precautions: Gas struts are under high pressure, so it's important to handle them with care. Never attempt to disassemble or modify a gas strut.
Conclusion
Matching the size of Bonnet Gas Struts to your vehicle may seem like a daunting task, but with the right measurements and a bit of knowledge, it can be done easily. Remember to consider all the factors, measure accurately, and choose the right force rating. If you have any questions or need further assistance, don't hesitate to reach out.
