Overview of Micro Gas Springs

Small gas springs, also known as mini gas springs or miniature gas springs, are compact hydraulic devices consisting of a cylinder filled with nitrogen gas and a piston rod. These components work in tandem to provide controlled force and motion. Small gas springs are typically smaller in size, making them ideal for applications with limited space.

Stainless Steel 316 Compact Micro Gas Struts

Common types

Standard Micro Gas Springs

Basic, reliable models designed to deliver consistent force throughout their stroke length.

Lockable Micro Gas Springs

Equipped with a mechanism to fix the spring position at any point during extension or retraction.

Dampened Micro Gas Springs

Feature built-in hydraulic or pneumatic damping to regulate movement speed and reduce impact.

Adjustable Micro Gas Springs

Allow real-time modification of output force to accommodate changing load requirements.

Components

Rod
Rods are either precision ground, polished carbon or stainless steel. The surface of the rod is treated to improve wear and increase corrosion resistance. In general, the rod will always be longer than the stroke of the spring and shorter than the length of the tube.

Tube
The tubes used are either powder coated carbon or stainless steel high integrity seamless welded tube suitable for high pressures.

Guide and Seal Package
Manufactured from plastic composite, the guide and seal package provide a bearing surface for the rod, prevents the escape of gas and ingress of contamination.

Piston Assembly
Manufactured from zinc, aluminium or plastic the piston assembly controls the rate at which the gas spring extends and compresses, it also serves to prevent the rod from being expelled from the spring. For safety reasons the integrity of the piston to rod attachment is critical.

End Plug
This is used to seal the tube end of the gas spring and is where the tube end fitting attaches. In the case of Camloc Gas Springs the end plug is also where the Vari-Lift valve is incorporated. The Vari-Lift valve allows the release of the Nitrogen gas from the spring, which reduces the gas spring force.

Nitrogen Gas Charge
Nitrogen is used as it is inert and non-flammable and therefore does not react with any of the internal components.

Oil
Provides lubrication for the seal and internal components, it also serves to provide the damping effect at the end of the gas springs stroke.

FAQ

Q: What is a micro gas spring?

A: A micro gas spring is a compact gas spring designed for precise, small-scale applications, providing controlled linear motion and damping in tight spaces.

Q: What are the main applications of micro gas springs?

A: They are commonly used in medical devices, laboratory instruments, electronics, robotics, automotive interiors, and aerospace components where space is limited and precise motion is required.

Q: What materials are used in micro gas springs?

A: The cylinder is usually stainless steel, carbon steel, or aluminum. Piston rods are chrome-plated steel, stainless steel, or titanium. Seals use NBR, polyurethane, or PTFE for low friction and durability.

Q: What is the typical stroke length of a micro gas spring?

A: Stroke lengths range from 5 mm to 100 mm, depending on the application and required force.

Q: What forces can micro gas springs provide?

A: Force ranges typically vary from 5 N to 200 N, adjustable according to gas pressure and cylinder size.

Q: Are micro gas springs adjustable?

A: Yes, some models allow adjustment of force or damping through valve mechanisms, providing precise control of motion.

Q: What type of gas is used inside micro gas springs?

A: Nitrogen is used due to its inert, stable properties, ensuring long-term consistent performance and safety.

Q: How long is the service life of a micro gas spring?

A: Depending on material, design, and application, typical service life ranges from 50,000 to 200,000 cycles. Stainless steel and high-quality seals significantly improve longevity.

Q: Can micro gas springs operate in extreme temperatures?

A: Yes, stainless steel versions with high-performance seals can operate between -40°C and +80°C. Specialized versions can go beyond this range for aerospace or industrial applications.

Q: Are micro gas springs corrosion-resistant?

A: Stainless steel cylinders and rods provide high corrosion resistance, while chrome plating and surface coatings further enhance durability in humid or corrosive environments.

Q: How do micro gas springs differ from standard gas springs?

A: Micro gas springs are smaller, designed for precise motion, limited space, and light-duty applications. They require tighter tolerances and lower friction than standard gas springs.

Q: Can micro gas springs be customized?

A: Yes, customization options include stroke length, force, rod diameter, mounting type, material selection, damping characteristics, and even special coatings.

Q: How are micro gas springs mounted?

A: They can be mounted via threaded ends, ball joints, clevis, brackets, or custom end fittings, depending on application requirements.

Q: Are micro gas springs maintenance-free?

A: They are generally maintenance-free due to sealed construction, but periodic inspection for wear or leakage is recommended in critical applications.

Q: How to ensure the right micro gas spring selection?

A: Factors include required force, stroke length, space constraints, operating environment, material preference, cycle life, and damping requirements. Consultation with suppliers is recommended for precise selection.
