Introduction: The Cheapest Pneumatic Cylinder Ever Possible! Less Than $2

By

Hi everyone,

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

Materials:

  • Syringe x2 ( 2ml - 4ml )
  • Metal rod (about 3mm)
  • Small washer

Consumables:

  • Rubber based adhesive
  • Super glue

Tools:

  • 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
