Push - Pull for a Hydraulic Cylinder

A hydraulic cylinder typically operates on the principle of push-pull motion. This means the hydraulic cylinder can either extend (push) or retract (pull) depending on the fluid pressure applied to either side of the piston.

Push Motion:

• The hydraulic fluid is pumped into the rod end of the cylinder.
• This creates pressure behind the piston, causing it to move and extend the cylinder.
• The force generated by the hydraulic pressure moves the rod outward.

Pull Motion:

• The hydraulic fluid is pumped into the head end (opposite the rod side) of the cylinder.
• This generates pressure behind the piston in the opposite direction, pulling the rod back into the cylinder.
• The force moves the rod inward.

Hydraulic cylinders can be used in both push and pull applications depending on the specific design and fluid flow configuration. For instance:

• Push application: Lifting heavy loads or pushing components.
• Pull application: Reaching and pulling loads or components back into a machine.
