Best Linear motion generating Linear actuator: Alio Industries

This type of actuator has a number of applications. For example, it is used in industrial machines and tools, valves, computer disk drives, printers, etc.

Types of Linear actuator:

• Mechanical:

In this case, circular motion is converted into linear motion. This is done with the help of a wheel or axel or screw etc. These actuators have competitive pricing. You do not require the power to use these actuators. However, this type of actuator is not automatic. It has to be operated manually.

• Hydraulic:

In this case, there will be a cylinder with a piston. Liquids are used to generate pressure. In this case, when pressure is applied to the piston, it will result in the movement of an external object. The Application of very high forces is possible in this actuator. But there can be leakage problems. You can use this actuator only if you have an external hydraulic pump.

• Pneumatic:

In this type of Linear motion generating actuators, gases are used for generating the pressure. This type of actuator can be used in a number of mechanical processes. But these can be very bulky. There can also be problems like leakage, and they are not as efficient as a mechanical actuator.

• Piezoelectric:

In this type of actuator, it is possible to generate small motion at high speed. You do not require much power to use this type of actuator. It is mainly used in fuel injectors. These actuators are expensive and need very high voltage. They are also delicate.

• Twisted and coiled polymer or supercoiled polymer:

This type of actuator is made from nylon, which is silver coated. It has competitive pricing, and it is also light in weight. But you have to use it at a very high temperature. These are not very efficient.

• Electro-mechanical:

In this too, the rotational motion is converted into linear motion. In this case, an electrical motor is used. It is available in different designs. It is a cost-effective option.  Automation is possible in this type of actuator. However, it can easily get subjected to wear and tear as it has many moving parts.

• Linear Motors:

From the name, it is clear that here the motor will move in a linear motion. The load capacity of this type of actuator is low. The design is simple. There are very few moving parts. It is possible to have high speed in this type of actuator. You can easily use this actuator in an outside environment.

• Telescoping linear actuator:

This special category of the actuator is used in those places and applications where space is a problem. You can easily use it in less space. This actuator has a very high range of motion.

Which type of Linear actuator you must use will depend on various factors. You will have to take into consideration the application for which you are going to use the actuator, your budget, space, etc.
