A hydraulic cylinder is a mechanical equipment for the transfer of power through the use of the action of high-pressure oil against the surface of a piston in the cylinder.

A hydraulic cylinder provides a linear force in an axis, either in one or two directions (known as a single-cylinder or double-acting respectively). There are many companies that provide services like Hydraulic Cylinders Install & Repair Service in Sydney, Brisbane & Perth.

The cylinder is generally composed of 4 or 5 members; Tube, Rod, piston (optional), Gland and Endcap

In a standard hydraulic cylinder with a piston, the oil is introduced at one end via a certain type of "port" and the piston is sealed to the tube by a seal double-acting and also between the stem and the gland by a joint single direction. In addition, you will usually find a seal wiper is used in the gland to keep dirt. This model is known as a double-acting cylinder.

In a single-acting cylinder, the oil acts only on one side of the piston, so that it can be mechanically moved in a direction.

In this cylinder design, the force is defined by the surface of the rod, whereas in a cylinder with a piston, the rod may be of any size and strength can be measured or regulated by the piston design.

Typically, one end of the tube and is fixed on the end of the rod is attached to the object to move, although it is possible to fix the end of the rod, and attaching the object is moved to the end of the tube.

The size of a hydraulic cylinder can be virtually limitless, typically a few centimeters in length to several meters, although in theory there are few limits.
