Optimize designs before prototyping
Document specifications for manufacturing
For DIY & Maintenance
Replace worn struts with proper equivalents
Upgrade existing systems safely
Troubleshoot lifting problems
Understand mechanical principles
Gas Strut Types and Applications
Our gas strut force calculator works with these common types:
1. Compression Gas Springs
Most common type (extends when unloaded)
Used for lids, hatches, and doors
Force ranges from 50N to 2000N
2. Tension Gas Springs
Extends under load (opposite of compression)
Used for pull-up applications
Common in medical and industrial equipment
3. Locking Gas Springs
Can be locked in position
Used for adjustable chairs, tables
Requires special mounting considerations
Installation Guidelines
After using our gas strut position calculator, follow these professional installation tips:
Mounting orientation: Rod end should typically point downward
Travel angle: Keep within 30° of strut axis for longest life
End fittings: Use proper ball joints or brackets
Pre-load: Install with slight compression (10-15mm)
Clearance: Ensure full extension/compression without binding
Common Mistakes to Avoid
When using our calculate gas strut size tool and installing struts:
Undersizing struts: Leads to premature failure
Incorrect mounting: Causes binding or uneven wear
Ignoring environment: Temperature affects pressure
Wrong stroke length: Prevents full opening/closing
Missing safety factor: Can lead to dangerous failures
Advanced Calculation Considerations
For precise results from our online gas strut calculator, account for:
Center of gravity: Affects actual torque requirements
Friction: Hinges and guides add resistance
Multiple struts: Divide load evenly between units
Temperature range: Gas pressure varies with heat/cold
Cycle life: Higher quality struts last longer
Pro Tip: For critical applications, order gas struts with 10-15% adjustable force range using special valves. This allows fine-tuning during installation.
Frequently Asked Questions
How do I measure for replacement gas struts?
Measure extended length, compressed length, and diameter. Our calculator helps determine required force based on your application.
Can I use two weaker struts instead of one strong one?
Yes, divide the total required force by the number of struts. Ensure even mounting on both sides.
Why does my gas strut lose pressure over time?
All gas struts slowly lose pressure (5-10% per year). Replace if force drops more than 20% from original.
How accurate is this gas strut calculator?
Our gas strut calculation tool provides professional-grade estimates within 10% of actual requirements for standard applications.
Final Thoughts
Properly specified gas springs make lids and panels effortless to operate while ensuring safety and longevity. Our gas strut calculator 2024 takes the guesswork out of selecting the perfect components.
