History of Hydraulic Cylinders and Fluid Power Systems

The development of hydraulic cylinders is deeply rooted in the evolution of hydraulic engineering and the application of fluid power. The story begins in 1648, when Blaise Pascal discovered Pascal’s Principle, which states that pressure applied to a confined fluid is transmitted undiminished in all directions. This foundational idea gave rise to the field of hydraulics and forms the scientific basis for all hydraulic systems used today.

While Pascal’s Principle provided the theoretical groundwork, it was not until 1738 that Daniel Bernoulli expanded on these concepts with Bernoulli’s Principle, combining them to develop systems capable of driving mills and operating pumps. These advances highlighted the advantages of using fluids under pressure to perform mechanical work, leading to early forms of hydraulic technology.

The turning point for hydraulic machinery came in 1795, with Joseph Bramah’s invention of the hydraulic press—a revolutionary device that used pressurized liquid between two cylinders of different sizes to amplify force. Bramah’s press not only transformed manufacturing but also established him as a pioneer in hydraulic system design. His innovation paved the way for more complex hydraulic applications and the eventual development of hydraulic cylinders as we know them today.

Progress in hydraulic technology accelerated in the 19th century, thanks to key figures such as William Armstrong. Armstrong’s hydraulic crane, which featured a hydraulic cylinder known as a “jigger,” transformed lifting and material handling processes. Innovations like these made it possible for entire industries to harness the power of pressurized fluids for lifting, moving, and shaping heavy materials with unprecedented efficiency.

Originally, water was used as the hydraulic medium in these systems. However, challenges such as corrosion, freezing, and inefficiency led engineers to adopt specialized hydraulic oils—fluids designed to reduce rust, minimize rapid evaporation, and enhance system reliability. The switch to hydraulic oil, more than 80 years ago, marked a major milestone, resulting in improved performance, longer equipment life, and greater efficiency in hydraulic machinery.

Since the mid-20th century, hydraulic technology has continued to evolve, with today’s hydraulic cylinders powering everything from construction cranes and mining equipment to advanced aerospace assemblies and precision robotics. Modern hydraulic machines are both more powerful and more prevalent, enabling engineers to build taller structures, create more efficient vehicles, and automate more processes than ever before.
