Gas springs have become a popular alternative to traditional coil-based springs. Also known as pneumatic springs, they consist of a gas-filled cylinder with a piston attached to the end. The piston is extended by default. When exposed to a compressive force, though, the piston will retract inside of the cylinder, thereby pressurizing the gas. The pressurized gas will then exert an outwards force, essentially pushing the piston against the object that’s compressing it. What benefits do gas springs offer exactly?

1. Low Maintenance: Unlike other types of springs, gas springs require little or no maintenance. They still consist of multiple parts. Gas springs have a piston, seals and attachments. However, these parts are enclosed in a cylinder, so maintaining gas springs is a breeze. You don’t have to worry about cleaning the parts, nor do you have to worry about oiling or lubricating them. With their self-enclosed design, gas springs are easy to maintain.

Advantages Of Buying A Gas Lift Storage Bed

With the increase in population and the reduction in the living spaces, it has resulted in limited storage space. People are inventing smart ways to increase the storage space and avoid clutter. The best discovery of all is the gas lift bed. These are the beds that have incorporated storage space beneath the mattress which has a gas lift mechanism to lift the mattress and easily access the storage space. Gas lift storage beds are also known as hydraulic beds and have guarded space that is practical as well as attractive. Storage of cushions, linen, clothes, sports equipment, toys, shoes, and other assets become

A linear actuator is an actuator that creates motion in a straight line, in contrast to the circular motion of a conventional electric motor. Linear actuators are used in machine tools and industrial machinery, in computer peripherals such as disk drives and printers, in valves and dampers, and in many other places where linear motion is required. Hydraulic or pneumatic cylinders inherently produce linear motion. Many other mechanisms are used to generate linear motion from a rotating motor. The combination of rare earth Magnets and high tech materials is what makes these very strong Linear Actuators exist. Its the electricity that run through these motor armature winding's and magnets used inside the motors that makes them so strong. Engineers can choose from various technologies such as electrical (electro-mechanical), hydraulic or pneumatic technologies when selecting linear actuators for motion control applications. In nearly all cases, an electrical actuator will prove to be the better choice due to a unique combination of characteristics.

How do gas struts work?

The basic principle of a gas struct is the same as for a mechanical coil spring; it is a device for storing energy. However, rather than straining the material that makes up the coil spring, a gas spring stores energy by compressing the Nitrogen gas contained inside. Although it looks similar to a pneumatic or hydraulic cylinder, a gas spring is different because of the fact that it does not require an external energy source to create movement. This is because a gas spring is a completely closed system and once manufactured and charged with inert nitrogen gas, no additional gas is introduced to the system. In gas springs, the pressure on either side of the piston remains equal whether it’s fully extended or fully closed. This again is different to a hydraulic or pneumatic cylinder that requires a pressure differential across the piston in order to move. So, if this is the case, how does it work if no further gas is introduced, and the internal pressure remains equal? The works because the gas strut extends and this is due to the difference in cross-sectional area of the rod where the gas is unable to exert any pressure. It is the difference between the nitrogen gas pressure acting on the internal face of the rod, and the atmospheric pressure acting on the external end of the rod that causes it to extend. As the rod is pushed into the tube the available volume is reduced, gas is compressed and the internal pressure increases, this compression creates the spring like behaviour. An orifice in the piston that is attached to the rod allows the flow of gas across the piston and controls the extension speed.

Features and Benefits of High-Speed Linear Actuators

When you check linear actuators, you will find out they are classified into different categories: Heavy-duty, Mini, Corrosion-resistant or Waterproof, and so on. But if you want to find out what a high speed actuator is, you will see that there is no standard classification. You will find just some guidelines on how to determine whether the actuator is actually high speed or not. But even those guidelines are vague. The mentioned guidelines consider a number of features. Those are the type of actuator, the drive mechanism, the industry. If you understand what these are, you will know which actuator you should choose. A drive mechanism is one of the limiting factors when it comes to the actuator speed. One more significant factor to consider is the actuator type. Usually, high-speed actuators are thrust-rod type actuators. They are called electric cylinders sometimes. These actuators are applied for pushing and pulling. And these operations require very short retraction and extension time. the speed of such actuators ranges from 0.1 m/sec and higher. High-speed actuators are normally manufactured for applications that operate non-stop. High-speed actuators shall deliver the top precision of movement, too. The leading actuator manufacturers know that the requirements for their products are high. So, reliable companies check that their actuators comply with the following requirements:
