Summary
The following technical information lets the reader know about hydraulic cylinders, their working, and their types. You can also find the correct selecting method for your hydraulic cylinders.
Hydraulic Cylinder is a linear actuator used to create mechanical force in any linear motion. Hydraulic energy is converted to mechanical movement through linear motion. The hydraulic cylinder uses pressurized hydraulic oil to generate power.
The hydraulic cylinder consists of two end caps, a tube, a piston and ram, and suitable oil seals. Typically, hydraulic cylinders have a piston attached to the rod's bottom. The pistons are sealed to the barrel. A piston allows the rod to be smaller than the barrel. This helps open up more surface area and volume on the rod side. The major purpose of the hydraulic cylinder is to create force or motion.

How does it work?
Hydraulic cylinders contain two cylinders with different diameters parallelly connected with a pipe. A portion of the assembly is filled with hydraulic oil incompressible by using two separate ports. A piston appears as a flat solid disk with a rod attached to its center. A force applied to the smaller piston will compress the fluid in the smaller cylinder. By connecting a tube to the smaller cylinder, fluid will flow from it to the larger cylinder. The piston of the larger cylinder then will move upwards with this generated force.
The pressure difference inside the cylinder is the key factor that makes the piston move. A cylinder reaches its maximum size when it is under continuous pressure. The pressure release valve will relieve this pressure, allowing you to move on.
Types
Double Acting
Double-acting cylinders are moved both forward and backward by a pressurized liquid.
Single Acting
Oil is expelled as the piston extends due to the pressurized fluid. The load and gravity will return to their original positions once the oil is exhausted.

Things to consider while buying a forklift hydraulic cylinder
Some of the cylinder specifications while buying a hydraulic cylinder are:
Operational Conditions
The operation conditions of hydraulic cylinders for various applications will be different. The hydraulic cylinder must be chosen in accordance with the change in operating conditions.
Fluid Types
The kind of fluid used for a hydraulic cylinder is crucial to the cylinder's operation. Most forklifts use the Triax forklift multipurpose hydraulic and transmission oil.
Materials of construction
The performance and durability of the hydraulic cylinder are affected by the used materials. This machine consists of a cylinder, a base, a head, and bearings. Typically, 1018 or 1020 mild steel alloys are used in the construction of forklift hydraulic cylinders.
Bore Size
At any given liquid pressure, it determines how much force can be developed. Thus confirm your requirement of force with respect to your bore size. The bore size for your forklift should be 0.5” less than the cylinder’s outer diameter.
Takeaways
Any linear motion is performed by hydraulic cylinders, which are linear actuators.
Two parallel cylinders are connected by a pipe to make a hydraulic cylinder.
Hydraulic cylinders are of two types double acting and single acting.
The type of fluid bore size and construction materials will determine which hydraulic cylinder is right for your forklift.
