650mm Gas Strut: Full Guide to Performance & Installation

Understanding the 650mm Gas Strut: What It Is and Why It Matters

A 650mm gas strut is a high-performance mechanical spring used primarily in automotive, furniture, and industrial applications. Measuring 650 millimeters in stroke length, these struts offer superior load support and consistent force over long-term use. Unlike standard gas springs, the 650mm variant is engineered for heavy-duty tasks such as holding heavy garage doors, truck tailgates, or heavy-duty workbench supports. Its robust design minimizes sagging and wear, making it a reliable choice for demanding environments.

Key Benefits of Choosing a 650mm Gas Strut

• High Load Capacity: Designed to handle up to 150 kg or more, ideal for heavy-duty door systems.
• Long Lifespan: Advanced piston seals and corrosion-resistant materials ensure durability beyond 10 years with proper maintenance.
• Smooth Operation: Precision-engineered internal mechanism reduces noise and friction during movement.
• Easy Installation: Compatible with most modern door systems; requires precise alignment but minimal tools.

Installation Tips for 650mm Gas Struts (2025 Standards)

Proper installation is critical to maximize performance and safety. Follow these steps carefully:

Step 1: Prepare the Equipment

Disconnect power sources if installing near electrical systems. Clean the mounting points thoroughly and verify the gearbox or support bracket matches the 650mm strut specifications.

Step 2: Align the Strut Correctly

Slide the strut into place, ensuring the piston rod aligns perfectly with the housing. Misalignment causes uneven force distribution and premature failure. Use a straight edge or laser level for precision.

Step 3: Secure Mounting Hardware

Tighten bolts evenly in a crisscross pattern to avoid warping. Apply thread locker if recommended by the manufacturer to prevent loosening under vibration.

Step 4: Test Functionality

With power disconnected, manually cycle the door to check smooth movement. Operate through full stroke—no binding, grinding, or unusual noise indicates installation errors.

Common Issues and Troubleshooting

Even with correct installation, issues may arise. Watch for:

• Stiff Operation: Likely due to low hydraulic fluid (check seals) or internal contamination. Flush system with manufacturer-approved cleaning solution.
• Noisy Operation: May result from air leaks in the piston rod or worn seals. Inspect rod ends and replace seals if damaged.
• Reduced Hold Force: Indicates seal degradation or piston wear. Schedule replacement of the entire strut if force drops by more than 20%.
