When selecting a gas spring, it is crucial to consider several important parameters to ensure optimal performance. The following are the key factors to keep in mind:
- Total Length of the Gas Spring (A):
This refers to the distance between the two mounting center holes when the gas spring is fully extended.
- Stroke Length (B):
The stroke length is the difference between the total extended length and the fully compressed length of the gas spring. For example, if the total extended length is 300 mm and the fully compressed length is 200 mm, the stroke length would be 300 mm – 200 mm = 100 mm. This value represents the distance the gas spring compresses.
- Relationship Between Total Length and Stroke Length:
When selecting the length of a gas spring, it is essential to pay attention to the relationship between the total length and stroke length. The following formula should be adhered to:
A (Total Length) ≥ B (Stroke Length) * 2 + 80 mm.
The additional 80 mm represents the minimum length required for components such as the guide sleeve, piston, and joints. Many customers have selected the wrong model due to overlooking this formula in the company’s selection guide. Therefore, it is imperative to follow this rule during the selection process.
- Gas Spring Force:
It is also critical to calculate the required force of the gas spring using the formula provided in the company’s selection guide. Ensuring the correct force calculation is vital for proper gas spring operation.
By carefully considering these parameters, the correct gas spring model can be selected, avoiding operational issues and ensuring a long-lasting solution.
