Small hydraulic cylinders for heavy-duty applications

A hydraulic cylinder is a mechanical actuator, typically consisting of a cylindrical barrel, a small hydraulic piston, and a rod, that takes pressure applied to the rod and converts it into linear force and motion. Hydraulic cylinders can handle both high force and controlled motion, making them essential in heavy duty applications, such as construction equipment.

The small hydraulic piston divides the cylinder into two chambers. When fluid is pumped into one chamber, the resulting pressure forces the piston to move. Because hydraulic fluid is incompressible, all of the pressure is transmitted directly to the piston, making the rod to extend or retract. This incompressibility allows precise piston control, which can be translated into a wide range of speeds and forces.

A hydraulic cylinder is designed to move in a linear direction and exert force, usually by pushing, pulling, or lifting heavy loads. They are typically found in applications that require both high levels of force and precise movement, such as in construction equipment, such as excavators and cranes, in manufacturing presses, automotive systems, such as braking, or any applications requiring substantial force in a small footprint.

You’ll find hydraulic cylinders in a variety of applications that require high force and precise linear movement. The construction industry uses small hydraulic cylinders in excavators, bulldozers, and skid steers to lift, push, and dig. Forklifts rely on hydraulic cylinders to lift heavy loads. Manufacturers use them in presses, injection molding machines, and stamping machines to move heavy dies or materials. Agriculture, automotive, aerospace, and mining industries also use hydraulic cylinders in various types of equipment.

Small hydraulic cylinders generate high force output in a compact space, making them ideal for applications that require high power but have limited space. They can squeeze into machinery that has tight clearances as well as in mobile equipment with tight space and weight constraints. It’s easier to integrate the compact components into most designs, and because Nason’s small hydraulic cylinders pack as much power as larger units, there’s no need to compromise performance. The high efficiency and precision of Nason’s cylinders make them an excellent choice for applications such as compact construction equipment, automotive systems, and small-scale manufacturing processes.

A hydraulic cylinder can move as fast as the flow rate of the hydraulic fluid being pumped into it. Faster fluid flow creates faster rod and piston movement. Slower flow allows for more controlled motion. Depending on cylinder size, fluid pressure, and the specific application requirements, small hydraulic cylinders can include both rapid movements and slower, more precise actions. Speeds often range from a few inches per second to several feet per second.

How much a hydraulic cylinder can lift or push depends on factors, including the hydraulic pressure, the piston size, and the cylinder design. You can calculate the amount of force exerted by the cylinder by multiplying the pressure of the fluid by the piston area. (F=PA)

Some miniature hydraulic cylinders have bore sizes as small as 0.25 inches (6.35 mm) and can operate at pressures up to 3,000 PSI (pounds per square inch), giving them a lifting force of 147 pounds. Industrial hydraulic cylinders used in construction equipment can lift anywhere from a few thousand pounds to over 100 tons, depending on the design of the system and how much pressure it can handle.
