Hydraulic Cylinder Terminology
The Gorilla Spares team has provided this glossary of terms for those new to hydraulics, and hydraulic cylinders in particular, to help you understand their importance.
- Barrel – This is the seamless body of the cylinder. Its main function is to contain cylinder pressure. It also guides the piston and provides a sealing surface for the piston seal.
- Base or Cap – The cap (or base) is connected to the cylinder body by means of welding, threading, bolts, or tie rod. Its main purpose is to enclose the pressure chamber at one end.
- Bore– This is the inside diameter of the cylinder tube. It determines the total power of the cylinder. The larger the bore, the more it can lift or push.
- Cushion– This is a mechanical device that is fitted into a hydraulic cylinder to close off the flow of fluid and slow it down before it reaches the end of the stroke.
- Cylinder, Double-acting – Double-acting cylinders can apply force and motion to both extend and retract a piston rod or sleeve from a cylinder.
- Cylinder, Single-acting – Single-acting cylinders can apply force in one direction only (to either extend or retract).
- Cylinder, Telescoping – This cylinder is constructed like a telescope and consist of a series of tubular rods called “sleeves” that decrease in size sequentially and are nested inside each other.
- Drift – Internal leakage in the cylinder across the piston causes fluid to physically move from one side of the piston to the other. This creates an uneven balance that results in cylinder movement or “drift”.
- Head– The cylinder head is on the other end of the cap and is typically attached to the body through threading, bolting, or using a tie rod. The head seals off the oil at the end of the cylinder, serves as the support or guide for the rod, and keeps the piston from falling out of the barrel.
- Piston – The main function of the piston is to separate the pressure zones inside the cylinder barrel. The difference in pressure between the two sides of the piston causes the cylinder to extend and retract.
- Piston Rod – The piston rod is also known as the cylinder shaft or ram. It is the round device that moves in and out of the cylinder. It can be solid or hollow and is usually plated or heat-treated to provide better wear and corrosion resistance.
- Port– Cylinder ports are threaded holes that are used to connect hydraulic fittings (used to introduce hydraulic fluid into the cylinder). Ports may be located on any side of the cylinder head and cap end covers.
- Seal gland – Seal glands are placed in the cylinder to stop pressurized oil from leaking past the connection between the rod and the head.
- Stroke– The stroke is the distance the piston can travel through the cylinder tube, from fully closed to fully open.
