Two Way Hydraulic Cylinder

HSG40 Series Two Way Hydraulic Cylinder

Cylinder Barrel: The body of the cylinder that handles internal pressure and ensures smooth piston movement.

Piston Rod: A sturdy piston rod that moves within the cylinder barrel to transfer the force generated by the hydraulic fluid to the intended application.

Piston: This component divides the cylinder into two chambers and moves the piston back and forth as hydraulic fluid is pumped into the cylinder.

End Caps: Securely fastened to the ends of the cylinder barrel, these hold the internal components in place and prevent fluid leakage.

Seals: These seals are critical to maintaining the integrity of the cylinder, preventing hydraulic fluid leakage and keeping out contaminants.

Rod Seal: It is part of the end cap that guides the piston rod as it enters and exits and contains the piston rod seal.

Ports: Inlets and outlets for hydraulic fluid, carefully arranged to control the movement of the piston within the cylinder.
