Ordering the right gas spring requires providing specific technical parameters to ensure perfect functionality for your application. Missing crucial details can lead to improper performance or compatibility issues.
When ordering gas springs, provide these four essential parameters: stroke/total length, force requirements (minimum extension force), intended application, and desired function (support, lifting, locking, etc). These specifications ensure proper product selection.
Why Is Stroke Length or Total Length Critical?
Understanding dimensional requirements is the foundation of gas spring selection:
-
Two Measurement Options:
- Stroke length (movement distance)
- Total extended length
- Providing either allows calculation of the other
-
Measurement Tips:
- For replacements: measure existing spring
- For new designs: consider full range of motion
- Account for mounting hardware space
How Should Force Requirements Be Specified?
Force parameters determine the gas spring's power and performance:
-
Understanding "Minimum Extension Force":
- Standard industry measurement
- The force at fully extended position
- Typically measured in Newtons (N) or pounds (lbs)
-
Force Calculation Factors:
- Weight of supported component
- Desired ease of operation
- Safety margins for heavy loads
Why Does Application Matter in Gas Spring Selection?
Different industries have unique requirements:
| Application | Special Considerations |
|---|---|
| Automotive | Weather resistance |
| Furniture | Quiet operation |
| Medical | Smooth movement |
| Industrial | High cycle life |
What Function Should the Gas Spring Perform?
Different mechanisms require different gas spring types:
-
Basic Functions:
- Support: Maintain position
- Lift: Assist raising motion
- Lower: Control descent
- Lock: Fix positions
-
Specialty Options:
- Position locking models
- Slow-close dampers
- Adjustable force versions
