Hydraulic cylinders generate linear force and motion from hydraulic fluid pressure. Most hydraulic cylinders are double acting, as hydraulic pressure can be applied to the piston or rod end of the cylinder to generate extension or retraction force, respectively. Hydraulic cylinders are used in many mechanical applications where high linear forces are required. With a relatively small hydraulic motor, a large cylinder can generate tens of tons of force, due to the almost unlimited mechanical gain capacity and inherent stability of hydraulic systems.

Hydraulic cylinder parts, parts of a hydraulic cylinder

Hydraulic cylinders consist of a smooth bore round tubular cylinder, a free-moving piston with various polymer seals, a highly polished round piston rod, and a rod support bearing along with various tight-fitting seals to seal the slide bar where comes out of the cylinder. The top of the cylinder, as well as the end of the piston rod, have clevis fittings that allow angular movement of the device to which the cylinder is attached. Each end of the cylinder has a threaded or compression connection opening where hydraulic pressure tubes connect from the cylinder control valve.

Cylinder operation, parts of a hydraulic cylinder

When the control valve handle is moved to the extended cylinder position, the hydraulic fluid is at high pressure, usually 500 pounds. to thousands of pounds. per square inch flows from the hydraulic pump to the piston side of the cylinder, while oil under the piston on the rod side of the cylinder can flow from the cylinder and back to the reservoir. If the handle is pushed to the retract position, the pressurized oil is sent to the side of the cylinder rod, retracting the cylinder and pushing the oil to the top of the piston and back into the reservoir.

System description, hydraulic cylinder parts

A typical system employing hydraulic cylinders to perform high force jobs, such as a hydraulic excavator shovel used to excavate in construction, consists of the motor-driven hydraulic pump, oil reservoir, cooling and filtering, controls operator, tubing and hydraulic cylinders.

Hydraulic gain, hydraulic cylinder parts

This provides a much greater output force from the cylinder than the force applied by the motor, albeit at a proportionally lower speed. In the case of hydraulic jacks, cylinders, and presses, this is exactly the point of using hydraulic cylinders – tons of force available at slow to moderate inches per minute.

Common Applications: hydraulic cylinder parts

Hydraulic cylinders are used in virtually all types of construction equipment, including excavators, bulldozers, backhoes, cranes, and graders. In buildings, hydraulic lifts use large compound telescopic cylinders. Large trash bins use hydraulic cylinders on mechanical cylinders to compact trash. In the automotive and transportation industry, hydraulic drum brakes and disc brake calipers consist of hydraulic cylinders. In industry, forklifts and jacks are widely used.

Domestic applications: parts of a hydraulic piston

Log splitters use hydraulic cylinder rams to split firewood cables during winter without twisting your back, swinging a mallet.
