Claims

[Claims for Utility Model Registration] A piston rod is attached to a cylinder equipped with a tube and head covers fixed to both ends of the tube by passing through the head covers at both ends, and both ends of the piston rod are fixed to end plates. Air is supplied to the cylinder chambers on both sides of the piston fixed to the piston rod through an air passage drilled along the axis, and thus,
In a fluid pressure cylinder for moving a cylinder, a linear bearing housing part extending in the axial direction is provided in the head cover at both ends, and a linear bearing is fitted between the housing part and the outer periphery of the piston rod to bear both ends of the cylinder. A wear ring is attached to the outer peripheral surface of the piston, and the wear ring is brought into sliding contact with the inner peripheral surface of the tube to support the cylinder, and an air passage bored in the piston rod is opened at both axial end surfaces of the piston rod. A fluid pressure cylinder characterized in that the opening is connected to an air passage provided in the end plate.
