Why are Rack&Pinion pneumatic actuators widely used?

What are the main reasons why Rack&Pinion Pneumatic Actuators are widely used in many industries?
1. The starting device has a simple structure and is easy to maintain. Its medium is air, which is not easy to burn and has high safety.
2. The working medium has low cost and does not pollute the environment.

3. High reliability and long service life.
 
4. It is very easy to adjust the output force and working speed.
 
5. Compressed air can be supplied centrally and transported over long distances.
 
6. By utilizing the compressibility of air, energy can be stored to achieve centralized gas supply. Energy can be released in a short period of time to achieve high-speed response during intermittent motion. Can achieve buffering. Has strong adaptability to impact loads and overloads. Under certain conditions, pneumatic devices can have self-sustaining capabilities.
 The above are the reasons why Rack&Pinion Pneumatic Actuators are widely used, and I believe everyone already understands.
