Small Hydraulic Cylinders
Small hydraulic cylinders can have strokes less than an inch in length. A stroke length represents the distance that the piston moves inside the cylinder to achieve its extended state. All hydraulic cylinders, no matter their size, convert hydraulic power to mechanical pushing and pulling power.
Small hydraulic cylinders have two main parts: the outer cylinder and the piston, which connected to a piston rod. The cylinder is commonly made of steel or aluminum, while the piston is generally chrome-plated to resist corrosion and wear. The inside of the cylinder is partially filled with hydraulic fluid, a substance usually composed of mineral oil, ether, or water compounds.
Although they retain all of the capabilities of larger hydraulic cylinders, small hydraulic cylinders are typically used in applications requiring high precision, as in military operations or robotics.
