In this Instructable We'll be showing you How to build the Cheapest and the most Efficient Pneumatic linear actuator.
Why was this Pneumatic Actuator created?
We were actually forced to find a cheap way to build a pneumatic actuator; The price of the actuators were too pricey for us to buy; It was a real deterrent to our progress. After a long struggle and several prototypes, We removed the need for costly tools and O Ring (replaced it with the rubber), so that it can be easily made by anyone in just 15min. The total cost for one cylinder is less than $2.
The given price is just the average price throughout the world
This costed us just 16 cents only!

Testing the Pneumatic Cylinder:
Step 1: Collect the Materials
- Syringe x2 ( 2ml - 4ml )
- Metal rod (about 3mm)
- Small washer
- Rubber based adhesive
- Super glue
- Wire cutter or hobby knife
- Thin screwdriver
Step 2: Preparing Body of the Cylinder
- Separate all the parts of the syringe
- Remove the nozzle of one syringe
- Make a hole near the end of the other syringe through the inside ( Yes, from the inside)
- Glue the nozzle to the hole using super glue
- Use the adhesive to seal it
Step 3: Making the Piston Rod
- Fix one rubber part to the metal rod using Super glue
- And also slide the washer into it
- Make a hole in the other rubber and insert it into the rod
- The rubber's cupped side should face away from the cylinder's body
- This will act as the o ring
- Now insert this and fix it using Super glue
Now your super cheap and efficient pneumatic cylinder is ready
