when piston rod is provided on both side of the piston, it is called as double piston rod double acting cylinder. 

Construction

  • It consists of cylinder body with end covers, the piston is fitted with piston seals.
  • The piston rod is extended and provided on both side of the piston. Hence area on both side of the piston is same.
Double acting double rod cylinder

Working 

  • When oil enters through inlet port A, it pushes the piston to complete forward stroke by draining the oil from the other port B.
  • When oil enters through inlet port B, it moves the piston to complete return stroke by draining the oil from the other port A.
  • As the area on both side of piston is same, it produces equal forces in both directions.
  • The area on both side is,

a= π/4(D-d)
D = Diameter of cylinder bore
d= Diameter of piston rod

Symbol 

Application 

  • It is used in table movement of grinding machine.
  • It is useful in robotic mechanisms where the rod is clamped at both ends and the body moves.
