The Evolution of Hydraulic Cylinders & Your Trusted Manufacturer

The history of hydraulic cylinders dates back to Pascal’s Law in 1647.

In 1795, the first hydraulic press using water medium appeared as the prototype of modern cylinders.

At the beginning of the 20th century, mineral oil replaced water, and double acting cylinders were widely used during World War II.

After 1950, two mainstream standards were formed:

✅ NFPA Standard (Square Head Tie Rod Cylinder) for North America, max pressure 21MPa

✅ ISO Standard (Round Head Tie Rod Cylinder) for Europe & Southeast Asia, nominal pressure 16MPa

Nowadays, tie rod hydraulic cylinders become the most popular actuator for general machinery, automation equipment.

After hundreds of years of technical evolution, reliable, standard-compliant hydraulic cylinders are essential for global industrial equipment.
