Tension Gas Spring Manufacturers | Pull-Type Gas Struts for Lids & Hatches
Discover the hidden force that pulls lids, hatches and guards back into place—smoothly, safely and without motors. Pull type tension gas springs are the ideal alternative for tight spaces and compact installations.
How it works (and why it’s different)
1. Free-state = Rod Retracted
2. Self-retracting Assist
Key Specifications Customers Ask For
- Force range 100-1 500 N (custom calibrations available)
- Closed length 200-450 mm; stroke 100-300 mm
- Single or double-tube design for different speed/curve behaviour
- End-fittings with anti-drop safety pin or wire
- Annual volumes 500-5 000 pcs, FOB + door-to-door freight
Where you’ll see it
Typical Applications
- Tractor engine hoods & side shields
- Sailboat hatches & storage lockers
- Automatic-retract safety guardrails
- Medical device lifting arms
- Prototype hardware
Single-tube vs. Double-tube
Single: faster retraction, steeper force rise (100 N → ~175 N over stroke).
Double: smoother, more linear curve (100 N → ~150 N) and reduced vibration—perfect when noise or precision matters.
Traction Spring vs. Pure Damper — Quick Pick
| Type | Free State | Opening Action | Closing Action | Assist? |
|---|---|---|---|---|
| Tension Gas Spring | Retracted (IN) | Pulled out by Gravity | Auto-retracts (Assisted) | ✓ Yes |
| Pure Damper | Neutral / Extended | Manual Pull (Resistance) | Controlled Descent (Resistance) | ✗ No |
* Pure Damper Note: A damper provides resistance in one or both directions to prevent slamming, but it does not store energy to return the application to its starting position. You must manually push it back.
