Telescopic Pneumatic Cylinder

Pneumatic cylinders or air cylinders are devices which use the power of compressed gas to produce a force in a reciprocating linear motion. Once actuated, compressed air enters into the tube at one end of the piston and, hence, imparts force on the piston. Consequently, the piston becomes displaced.
Engineers sometimes prefer to use pneumatic cylinders because they are quieter, cleaner, and do not require large amounts of space for fluid storage., Because the operating fluid is a gas, leakage from a pneumatic cylinder will not drip out. pneumatic cylinders vary in appearance, size and function.
