Selecting the right heavy duty gas strut can make all the difference between smooth, reliable operation and frequent mechanical issues. Whether used in industrial machinery, transportation equipment, or ergonomic systems, gas struts must be precisely matched to the application’s load, environment, and motion requirements. As a leading supplier and innovator in motion control solutions, Schutts Industrial provides expert guidance, precision-engineered products, and custom solutions to help customers make the best selection for their needs.
This guide will walk you through the key factors to consider when choosing the right gas strutfrom size and pressure to environmental durability all with insights from Schutts Industrial’s years of engineering expertise.
- Understanding the Basics of Heavy-Duty Gas Struts
A heavy-duty gas strut consists of a sealed cylinder filled with high-pressure nitrogen gas and a piston rod that moves in and out of the cylinder. The gas pressure provides the lifting or damping force, while a small amount of oil controls motion and provides cushioning. These components are used in applications where manual lifting would be difficult, or where precise and repeatable motion control is necessary.
Unlike mechanical springs, gas struts offer controlled speed, smoother action, and better resistance to wear. Schutts Industrial designs and manufactures heavy duty gas struts that are optimized for high-performance operation under demanding loads ensuring safety and reliability over thousands of cycles.
- Determine the Application Requirements
Before selecting a gas strut, it’s essential to identify the application parameters. The right choice depends on how and where the strut will be used. Consider the following:
- Load weight: Determine the maximum weight that the strut will need to lift, support, or counterbalance.
- Operating angle: The installation angle affects how force is distributed.
- Frequency of use: Frequent cycling demands higher-quality seals and robust materials.
- Mounting orientation: Some struts are designed for rod-up, rod-down, or horizontal installation.
- Environmental conditions: Consider exposure to dust, moisture, temperature fluctuations, or chemicals.
Schutts Industrial’s engineers assist customers in calculating exact specifications ensuring each heavy-duty gas strut performs flawlessly in its intended application.
- Force Rating and Pressure Calibration
The force rating (usually measured in newtons) is the most critical specification of a gas strut. It determines how much lifting or support force the strut will provide. Choosing the wrong pressure can lead to either excessive resistance or inadequate support.
Schutts Industrial uses advanced gas calibration technology to precisely set the nitrogen pressure within each strut. This allows for consistent and repeatable performance. Custom force tuning ensures that the gas strut delivers optimal lifting strength, preventing overloading or jerky movement.
- Material Selection and Durability
Not all gas struts are built to withstand the same conditions. The choice of materials significantly affects performance and lifespan.
Common material options include:
- Carbon steel: Ideal for general-purpose indoor applications.
- Stainless steel: Provides superior corrosion resistance for marine, medical, and outdoor environments.
- Epoxy or zinc-coated finishes: Offer extra protection in harsh or abrasive settings.
Schutts Industrial’s heavy duty gas struts are constructed from high-strength materials with advanced coatings that resist corrosion, moisture, and impact damage. Their commitment to quality materials ensures consistent performance even in extreme industrial environments.
- Stroke Length and Mounting Configuration
The stroke length refers to the distance the piston rod can extend or retract. It directly affects how far an object can open or close. Choosing the correct stroke length is crucial for ensuring that motion is both smooth and safe.
Mounting configuration is equally important. Gas struts must be installed at specific points to distribute load efficiently. Schutts Industrial provides technical drawings and guidance for proper installation geometry, ensuring maximum operational efficiency and lifespan.
- Damping and Speed Control
Smooth, controlled motion is one of the hallmarks of a well-engineered gas strut. Damping determines how quickly the piston moves and how softly it stops. In heavy duty applications, poor damping can cause abrupt closures or unsafe operation.
Schutts Industrial uses precision hydraulic oil and valve systems to regulate speed and damping performance. This ensures that every heavy-duty gas strut provides a quiet, stable, and reliable motion profile.
Conclusion
Selecting the right heavy duty gas strut requires understanding the balance between force, motion, and environmental demands. With the right expertise, the right materials, and precise engineering, gas struts can enhance safety, efficiency, and ease of use across countless applications.
