Hydraulic cylinders enable efficient power transmission in everything from heavy industrial machinery and vehicles to advanced lifting systems. This invention is used in a wide range of applications worldwide. More importantly, this is our specialty.

About us Our products

A cornerstone of industrialism

The principles of hydraulics originate from the early 17th century and have evolved over centuries into today's advanced hydraulic systems. The use of hydraulic cylinders began in the 19th century, revolutionising power transmission in agriculture, industry, and construction. This invention has paved the way for versatile and efficient technologies worldwide. Modern society would certainly not be the same without hydraulic cylinders.

Converting preassure to motionPut simply, a hydraulic cylinder consists of a tube, a rod, and a piston that generate mechanical movement through hydraulic pressure. By pressurising hydraulic fluid in different parts of the cylinder, the rod moves in various directions, enabling forward and backward motion based on where the pressure is applied. Hydraulic cylinders play a vital role in converting hydraulic energy into mechanical energy, and they can be used in a broad spectrum of machinery and systems, including agricultural equipment, construction machinery, and vehicles. The ability to deliver strong performance with precise control makes the hydraulic cylinder essential in engineering and industry. Ongoing advancements have unlocked new possibilities and improved performance across diverse applications, affirming its status as a remarkable invention.

Single-acting, double-acting and much moreModern hydraulic cylinders are complex and include components such as seals, bushings, and valves to enhance performance and reliability. There are also different types of cylinders, such as single-acting and double-acting variants, used in various ways depending on the need for motion and power transmission in specific applications. Single-acting cylinders use hydraulic pressure to move the rod in one direction only. The return to the starting position is achieved through gravity or a spring. In a double-acting cylinder, the rod moves in both directions by applying pressure to opposite sides of the piston.

Hydraulic cleanliness throughout production

The modern hydraulic cylinder is defined by its hydraulic cleanliness, a critical factor for its efficiency and long-term durability. For starters, the purity of hydraulic fluid and system components is vital, as contaminants can significantly impair performance, increase wear, and lead to system failures. That’s why cleanliness is a matter that demands meticulous attention throughout our manufacturing process.

Cleanliness is assessed according to ISO standards that specify permissible particle sizes. Hydraulic systems can be contaminated by particles from component wear, such as cylinders and valves, as well as by dirt and dust from the environment. At PMC Cylinders, we adhere to ISO 4406 standards to classify and monitor particle levels in hydraulic fluids. Moreover, we tailor cleanliness standards to meet your specific requirements.
