Gas springs are an effective alternative to coil die springs in applications that require extreme force. They operate by compressing nitrogen gas that is held within the spring cylinder. When compressed, the nitrogen gas volume decreases and creates a counter force against the rod that is being compressed.

Nitrogen gas springs exhibit impressive strength and can generate remarkable force relative to their size. The primary purposes of gas springs are to apply force, making them suitable for use in a wide range of manufacturing applications, specifically in the metal stamping industry. Today, gas springs are commonly found in stamping plants, tool and die, manufacturing, and various OEM applications.

Benefits of Using Gas Springs

Gas springs serve the same basic purpose as traditional coil springs, but choosing to implement gas springs into your manufacturing process can offer several functionality-enhancing benefits. Benefits include the following:

  • 1. Compact Design

    1Compact Design

    When properly installed, gas springs benefit from long life expectancy. Gas springs can last well over 2,000,000 cycles during standard normal operating conditions. Gas spring life is determined by many factors including, temperature, conditions of the environment, and speed of compression just to name a few. When conditions are optimized gas springs can be used for years before replacing.

  • 2. Long Lifespan

    3Safety Features

    At Special Springs, our gas springs include features designed to protect against four significant safety concerns — contaminants, uncontrolled speed, over stroke, and overpressure. These pose a risk to personnel and can cause irreparable damage to the cylinder. Safety features include:

    • Overpressure Active Safety

      Overpressure Active Safety: This feature eliminates the risk of overpressure and resulting structural failure by exhausting excessive pressure in a controlled manner through the bottom of the cylinder.

    • Over Stroke Active Safety

      Over Stroke Active Safety: This feature eliminates the risk of overpressure and resulting structural failure by exhausting excessive pressure in a controlled manner through the bottom of the cylinder.

    • Uncontrolled Speed Active Safety

      Uncontrolled Speed Active Safety: This feature eliminates the risk of overpressure and resulting structural failure by exhausting excessive pressure in a controlled manner through the bottom of the cylinder.

    • Active Protection Against Contaminants

      Active Protection Against Contaminants: This feature eliminates the risk of overpressure and resulting structural failure by exhausting excessive pressure in a controlled manner through the bottom of the cylinder.

Gas Spring Applications

Gas springs are used in many sectors of the manufacturing industry.

Specific applications of gas springs include metal stamping, tools, and die and some Original Equipment Manufacturer (OEM) applications. Gas springs are used in these applications for their instant force and large variety of stroke lengths available.With the right design, a nitrogen gas spring cylinder can deliver a significant force, explaining why gas springs are widely used in applications like metal stamping. In stamping press applications, the nitrogen cylinders must exert enough force to stamp and form shapes out of tough metals like solid steel.
