Nitrogen Gas Spring Information

What is Nitrogen Gas Spring

A Nitrogen Gas Spring, also known as a gas strut or gas spring, operates by filling a sealed cylinder with high-pressure nitrogen gas. The nitrogen gas is non-combustible, non-toxic, and odorless. The external force compresses the nitrogen gas through a piston rod. When the external force is removed, the elastic force is obtained by the expansion of the compressed nitrogen gas, making it a nitrogen gas spring.

History of Nitrogen Gas Spring

The development of nitrogen gas springs started around 60 years ago. Bordignon became the leading company in the market by developing new technological solutions applied to springs and nitrogen gas springs.

Purpose of Nitrogen Gas Spring

Nitrogen Gas Springs serve multiple purposes:

• Provide Elastic Force: They provide a consistent and immediate force over the entire stroke length, which is useful in various industrial applications.
• Compact Design: Nitrogen gas springs are compact and can produce a large initial elasticity in a small space without preloading.
• Stable Output: The elastic pressure increments are small during the working process of the mold and can remain relatively constant.
• Long Service Life: They are durable and have a potential useful life of hundreds of thousands to millions of cycles.
• Adjustable Force: The elastic force and stress point can be adjusted conveniently and accurately, which is helpful for mold design and debugging.
• Quality Assurance: Ensure stable quality of stamping parts, improve product quality, shorten mold change and adjustment time, increase productivity and reduce product costs.

Principle of Nitrogen Gas Spring

The principle of a nitrogen gas spring involves the use of a flexible sealing lip that contacts the rotating shaft to prevent fluid leakage. The lip is designed to maintain contact with the shaft under various operating conditions, including pressure changes and temperature variations. The hydrodynamic action of the rotating shaft helps to enhance the sealing effect.

Features of Nitrogen Gas Spring

Some key features of Nitrogen Gas Springs include:

• High Pressure Handling: Capable of handling high pressures, making them suitable for heavy-duty applications.
• Multiple Lips: Some nitrogen gas springs have multiple lips for enhanced sealing, providing better protection against leakage and contaminants.
• Customizable: Nitrogen gas springs can be tailored to meet specific application requirements, including operating performance, cost, and delivery.
• Reliability: Properly designed and maintained nitrogen gas springs can significantly extend the life of the equipment they serve.

Types of Nitrogen Gas Spring

There are several types of Nitrogen Gas Springs, primarily differentiated by their design and application:

• BE Series: Extra compact for use in space-limited die set applications.
• CE Series: Sub-compact for high force stroke lengths in a small space.
• LE Series (ISO Line): Meets all ISO and VDI piston rod, body, and height standards, as well as mounting and charge port specifications.
• SE Series (Renault Line): Conforms to Renault’s mounting, charge port, and body height requirements.
• PE Series (Performance Line): Offers similar forces, body lengths, and stroke lengths to both the LE and SE series die springs in a more narrow body diameter.
• M Series: A versatile line of semi-compact springs in a range of forces, stroke lengths, and body lengths.
• T Series: A super-compact series that features one third more force than the BE Series in similar-sized, bore-seal housings.
• H Series: Die springs with maximum force capacity that also retain the compact size of a gas spring.
• R Series: Featuring a threaded exterior body for secure installation and convenience.

Precautions for using Nitrogen Gas Spring

When using Nitrogen Gas Springs, consider the following:

• Proper Installation: Ensure the nitrogen gas spring is installed according to the manufacturer's instructions to ensure proper operation and prevent damage.
• Regular Maintenance: Periodically inspect and maintain the nitrogen gas spring to ensure its performance and longevity.
• Operating Conditions: Ensure the nitrogen gas spring is suitable for the operating temperature and pressure of the system to prevent failure.
