How Hydraulic Cylinders work

Hydraulic Cylinder

An example of a hydraulic cylinder

Hydraulic Cylinders, used to help with the lifting, pushing, dumping, hauling, crushing, drilling and digging they’re maybe one of the most important mechanical inventions which has fitted around us.

When manufacturing a hydraulic cylinder the process is now a lot more streamline with much tighter tolerances, the sheer amazing amount of force a hydraulic cylinder can produce is based upon a mechanical principle of pressure. The way the pressure is worked out is by this formula – Area X Psi = Force.

Hydraulic Cylinder – More Explanation

The hydraulic cylinder has main parts which make up the mechanism which includes the Piston, a piston seals, rod and the gland and butt.

The Rod which the piston is attached to is attached to a large nut at one end, as one of the hardest working component it’s extremely strong to resist bending and is also made out of steel. The piston inside the hydraulic cylinder is used to help build pressure and is done by using a piston seals to keep pressure from bypassing each other.

The Gland is also known as the head of the cylinder and helpes the rod retract and extend, this part contains wiper and rod seals to help keep contamination out of the hydraulic cylinder.


So there you have it, this simple but yet extremely useful mechanism is built using simple parts with very good accuracy in determining the amount of pressure each hydraulic cylinder can produce.
