Gas Springs

A dynamic gas spring (also known as a gas strut) is a sealed cylinder filled with pressurized nitrogen gas and oil. Gas springs use compressed gas to exert force and provide smooth, controlled motion in lifting, lowering, and positioning applications. What makes it dynamic is its integrated hydropneumatic damping system, which regulates extension speed and provides smooth, cushioned motion — especially near the end of the stroke. This precision is achieved through a specialized groove design. Additionally, by presetting the filling pressure, the gas spring can be optimized for any specific installation requirement.

Whether you’re opening a vehicle hood, lifting a machine panel, or adjusting medical equipment, TRAC Ultra Lift™ gas springs reduce manual effort, eliminate jerky movements, and improve operational safety.

Key characteristics:

• Automatic lift once opened slightly (~10°)
• Soft, vibration-free extension
• Controlled deceleration before full extension
• Compact, self-contained unit

Our gas springs are engineered to perform in demanding environments and are customizable for your specific application.

Advantages of Dynamic Damping Gas Springs:

• Dynamic Hydraulic Damping
  Provides smooth, vibration-free, and silent motion throughout the stroke, enhancing user comfort and product quality.
• Custom Stroke & Force Options
  Tailored extension force (50N–2500N) and stroke length to match your specific load and application needs.
• Soft End-of-Stroke Deceleration
  Built-in damping grooves ensure gentle and impact-free closing at the end of the stroke.
• Corrosion-Resistant Finishes
  Available with powder-coated surfaces for long-lasting durability in harsh environments.
• Maintenance-Free Construction
  Sealed, gas-filled design eliminates the need for lubrication or servicing.
• Long Cycle Life
  Engineered for over 50,000+ reliable operating cycles under rigorous conditions.
• Compact & Easy to Install
  Self-contained unit with flexible mounting options and minimal space requirements.
• Defined & Silent Extension Speed
  Ensures controlled, cushioned movement with smooth, noiseless operation from start to finish.

Engineering-Led Product Development for Gas Springs

Our strength lies in our in-house engineering capabilities, which allow us to design and develop gas springs that meet exact load requirements, space constraints, and damping characteristics.

To meet the tight tolerances and precision requirements of dynamic gas springs, we’ve built a fully-equipped in-house tool room designed for speed, accuracy, and durability.

Key Capabilities:

• High-precision dies for piston rods, end fittings, and cylinder components
  CNC Wire Cut, ZNC EDM, and Vertical Machining Centers for consistent part quality
• CAD/CAM-integrated workflows to ensure toolpath accuracy and rapid prototyping
• Extended tool life and dimensional stability to reduce downtime and cost over long production runs

This vertical integration allows us to maintain full control over quality and delivery timelines — from prototype to production.

• Certified Excellence: Manufactured in facilities certified to IATF 16949 (Automotive Quality Management) and ISO Standards for consistent, world-class quality.
  We maintain stringent quality control to ensure every TRAC Ultra Lift™ gas spring performs reliably in real-world conditions:
• Leakage Tests: Thorough nitrogen gas leakage inspections
• Reliability Tests: Endurance tested for 30,000–50,000+ cycles
• Thermal Tests for Oil Seals: SKF Germany oil seals tested from –30°C to +80°C
• Real-Application Tests: Validated under simulated operational environments
• Salt Spray Tests: Corrosion resistance tested for 250–500 hours
• Torque/Force Inspection: 100% force inspection for consistency and accuracy
