The actuator is a piece of mechanical equipment that can help us achieve automation. According to the motion mode, actuators can be divided into linear actuators and rotary actuators. According to its different motion modes, the actuator can be applied in different industries and equipment. In this article, we will briefly introduce to you the difference between linear actuators and rotary actuators.

Linear Actuator
The linear actuator moves in a straight line direction. It is like a robotic arm, which can be extended or shortened and can be used to move objects repeatedly.
Linear actuators are easy to operate and can be used in automated processes. Its advantages include smooth operation, precise positioning, easy maintenance, and long working life.

The main function of this actuator is to improve, lower, push and pull, which can serve the following industries:

● Automation equipment
● Packaging Machinery
● Industrial vehicle
● Material handling
● Print
● Machine tool
● Food processing
Rotary Actuator
The rotary actuator generates rotary motion through the shaft, such as controlling the ball valve/butterfly valve to rotate 90 degrees to open or close the valve. Rotary actuators can select the rotation angle according to industry needs to perfectly match the needs of the industry.

The advantages of rotary actuators include high torque, wide application range, easy maintenance, easy installation, and being suitable for harsh environments.
 
The main function of the rotary actuator is to drive the valve to open or close by rotating, which can serve the following industries:

● Water treatment industry
● Petroleum and natural gas
● Paper and pulp industry
● Shipbuilding
● Smart irrigation

Summarize
Linear actuators are more suitable for use in automated machinery, and rotary actuators are more suitable for automated industry. The working principles and motion modes of the two are different, which also leads to different application areas for the two.
