13 best mechanical gas springs

Mechanical gas springs, also known as gas struts or gas lift supports, are devices designed to provide controlled, linear force in mechanical applications. They are commonly used in various industries, including automotive, furniture, industrial equipment, and aerospace.Here are some key features and uses of mechanical gas springs:

  1. Working Principle: Mechanical gas springs operate based on the principle of gas compression. They consist of a sealed cylinder filled with a specific gas, typically nitrogen, and a piston rod. When force is applied to compress the spring, the gas inside the cylinder is compressed, creating pressure. This pressure generates a restoring force that opposes the compression, providing support or resistance.

  2. Adjustable Force: One of the advantages of gas springs is their ability to provide adjustable force. By varying the amount of gas inside the cylinder or by altering the piston rod's dimensions, the spring's force can be customized to suit specific application requirements.

  3. Lifting and Counterbalancing: Gas springs are often used for lifting and counterbalancing applications. For example, they are commonly found in the tailgates of cars, hoods of vehicles, and the lids of storage containers. They make it easier to open and close heavy objects with minimal effort.

  4. Damping and Control: In addition to providing lifting force, gas springs can also be equipped with damping mechanisms to control the speed of motion. This is useful in applications where a smooth, controlled movement is required, such as in office chairs or adjustable desks.

  5. Safety Features: Gas springs are designed with safety in mind. They typically include features such as end fittings and brackets that prevent sudden or uncontrolled release of gas, reducing the risk of accidents.

  6. Durability and Reliability: Gas springs are known for their durability and reliability. They can withstand a large number of cycles without significant loss of performance, making them suitable for long-term use in various applications.

  7. Variety of Sizes and Configurations: Gas springs come in a wide range of sizes and configurations to accommodate different load capacities and stroke lengths. This versatility allows them to be used in various applications.

  8. Installation: Proper installation is crucial for the safe and effective use of gas springs. Mounting brackets and hardware should be selected and installed according to the manufacturer's recommendations.

  9. Maintenance: Gas springs generally require minimal maintenance. However, periodic inspection for leaks or damage is recommended to ensure continued performance and safety.

In summary, mechanical gas springs are versatile devices that provide controlled linear force and are used in a wide range of applications where lifting, counterbalancing, and controlled motion are required. They offer adjustability, durability, and safety features, making them valuable components in the realm of power transmission products and industrial applications.

User questions & answers

Question: Looking for a Spring closed 9 1/2" long open & 15" open
Answer: Greetings: We would need all of the numbers that are on your old support to determine the pressure.
Question: I have gas supports P/N 3N300-52871 what will work for me
Answer: just type in model you need and search gas door supports or camper supports. likely many will fit your needs
Question: I have a 1996 ford ranger p/u, the length of the old struts is 17-1/2" hole to hole, the extended length is 19". Will these work on my truck
Answer: Greetings: Many supports even though they are the same length have different pressures. On you old supports there should be some part numbers. Send us those and we can point you to the correct listing.
Question: I built a chest and need these for the top. how do i know these are not overkill. the chest top is 66' wide by 22' deep and made out of mahogany
Answer: re:66"x22" its a little overkill. This application could use a little lighter gas spring, depending on the weight. I use them on a heavy canopy door and they work very well.
