Types of Hydraulic Cylinders

use hydraulic pressure to actuate the rod to extend and retract in both directions.
are designed for high pressures, high flows and rugged environments. Heavy duty cylinders are particularly suited to demanding industrial and mobile applications.
have significantly smaller and lighter designs than standard cylinders, which saves substantial weight and space in equipment. High pressure hydraulic cylinders are used in applications that need high forces and short or medium strokes, such as material testing and material transforming.
make the appartus that changes hydraulic fluid into mechanical power.
are short, cylinder shaped discs housed within cylinder barrels in order to compartmentalize the enclosed space within hydraulic cylinders.
are the large output pistons.
are devices that convert pressured fluid into mechanical power. Hydrolic is a common mispelling of hydraulic.
are designed for a multitude of applications in which a large force is required in both the push and pull directions.
are used in many applications, such as snowplows, construction equipment, personnel lifts and material handling equipment.
are manufactured and installed in older equipment with outdated cylinders. Replacement cylinder manufacturers offer products that will update machinery with the newest cylinder technology.
use hydraulic pressure to actuate the rod in only one direction.
can have strokes of less than an inch and are used in applications that require extreme precision.
are linear actuators designed specifically for highly corrosive environments as well as those where hygienic cleaning is essential to industrial processes.
are two-way hydraulic cylinders that provide a faster starting stroke and a subsequent, more powerful working stroke.
have multiple stages which enable longer strokes to be achieved, while utilizing less space.
have their head gland threaded on and the threads are protected by an o-ring.
use one or more steel rods, which are installed on the outside diameter of the cylinder housing, to provide extra stability. Cylinder tie-rods commonly bear a large portion of the applied load.
are made of a heavy duty, smooth welded housing for increased stability. Most housings of hydraulic cylinders are made of multiple parts, but not in the case of welded cylinders.

How does a Cylinder work
It has previously been noted that “Pascal’s Law” applies to confined liquids. Thus, for liquids to act in a hydraulic fashion, it must function with some type of enclosed system. An enclosed mechanical system that uses liquid hydraulically is known as a hydraulic power pack or a hydraulic power unit. Generally speaking, these packs/units consist of a reservoir (to store unused hydraulic fluid), a pump (to supply the rest of the hydraulic system with fluid), various types of tubes (to transport the hydraulic fluid), and actuators (devices that actually convert the energy produced by hydraulic liquid flow into mechanical power.)
Hydraulic cylinders form a major type of hydraulic actuator. The other major type of actuator is a hydraulic motor. The main difference between hydraulic cylinders and hydraulic motors lies in the fact that hydraulic cylinders primarily produce linear mechanical motion while hydraulic motors primarily produce rotary mechanical motion.
Although a hydraulic power pack is designed overall to harness the energy of fluid transmission, the cylinders represent the part of the pack where energy conversion truly takes place. Within the cylinder (or cylinders, as there are sometimes several) is a gear system and two valves alongside the piston. On one end is the intake check valve, with the discharge check valve being located on the opposite end. (As with the cylinder, some systems have just one piston or gear cog while others have multiple.)
Within a hydraulic system, tubing and a pressure vessel (or hydraulic pump) are needed to store and transport the fluid. When pressurized hydraulic fluids are introduced to the vessel, it presses upon the piston and engages the attached rod. When the pump is working, the piston is withdrawn. This creates a vacuum that draws hydraulic fluid from the reservoir, through the hosing and intake valve and finally into the cylinder. When the piston is returned to its original position and the check valve closes, the fluid becomes pressurized. This pumping action is repeated at variable speeds until enough pressure has been built up in the cylinder to force the fluid to pass through the discharge valve. This creates the energy needed to work the attached machinery and move the intended load.
Direction is determined by what side of the piston meets with the pressurized fluid. Fluid above the piston will retract the rod, while fluid below it will cause it to extend. The introduction of various amounts of pressurized hydraulic fluid on either end controls the movement of the piston, rod and attached load.
