When you need to dampen a generated force in an industrial environment, you must turn to a specific type of spring. For many years, people in your situation would use a coil-based spring similar to those found on an average automobile. However, many companies will use pneumatic springs, also known as gas traction, these days. Why are these better, and what advantages could they give you in your operation?
How Gas Traction Springs Work
Gas traction springs feature a cylinder that incorporates a piston and is filled with gas. When force is applied, the piston will push further down the cylinder and pressurise the gas. The gas will then produce resistance and create an opposing force, pushing against the compressive item.
Gas traction springs are superior to their predecessors for a number of reasons. For a start, they require very little maintenance. Those old-fashioned springs are exposed to the elements and will eventually wear out. As they do, they lose their ability to counter the generated energy and will need to be replaced.
All of the components within a gas traction spring are protected from the elements and relatively simple to repair or replace. You won't need to lubricate any of the parts, and you should expect the solution to outlast a traditional coil.
There are two separate types of gas traction springs. Some are kitted out with a locking mechanism for applications that would benefit from this approach. So the internal rod can be locked at any position within its range of travel. You'll often find this solution in a simple office chair, where gas struts "freeze" in one position, which is most comfortable for its occupant. Where you do not need a locking capacity, it's good to know that a nonblocking variety is also available.
Sometimes, it's important to restrict the range of motion to avoid unwanted movement. In an application like this, a gas traction spring is perfect as all the moving parts are contained within the cylinder, and the movement itself is always relatively small.
Expect gas traction springs to last far longer than those that rely on pure mechanical action. Perhaps this is why they can be found in many applications across various industries.
