Hydraulic cylinders are linear hydraulic motors that turn the hydrostatic power of a fluid into mechanical power. Typically, the hydraulic fluids utilized in the cylinder are oil, most commonly used in industrial applications, and water. Hydraulic cylinders consist of a plunger or piston inside a cylindrical housing. The bore of the cylinder must be perfectly cylindrical to prevent any obstruction of the piston. Piston seals prevent internal leakage from the high pressure side of the hydraulic cylinder to the low side. Rod seals are used to prevent external leakage. Piston rods, which move in and out of the hydraulic cylinder, are usually hard chrome plated to provide protection from corrosion and wear resistance. Hydraulic cylinder distributors most often offer their products in steel, stainless
steel or aluminum.
Hydraulic cylinder distributors can supply single action hydraulic cylinders or double action hydraulic cylinders. A single-acting hydraulic cylinder is configured for motion in only one direction, either pulling in or pushing out. An internal spring is used to provide plunger return when the hydraulic pressure is removed. In single-action hydraulic cylinders, less valving and plumbing is needed than in double-acting hydraulic cylinders. The more complex double-acting hydraulic cylinder is pressurized to move in both directions along the vertical or horizontal plane, or any other plane needed. These custom hydraulic cylinders provide higher speed operations and tighter control than single-acting hydraulic cylinders, and are less sensitive to system back pressures that can occur due to long tube lengths in telescopic cylinders.
Telescopic cylinders have strokes that extend far beyond that of a
standard hydraulic cylinder. Telescopic cylinders are multi-stage
hydraulic cylinders
that are ideal for applications in which there are severe space limitations.
Telescopic double-acting hydraulic cylinders are highly complicated,
as they actually consist of three or four concentric tubular components.
These custom hydraulic cylinders and components need to be manufactured
to a high degree of precision and accurately put into position with
precise clearances. The outer piston must have all the characteristics
of a hydraulic
cylinder body from the inside and all the features of the piston
rod on the outside. Special provisions are made to allow the passage
of fluid
up to the inner hydraulic cylinders. Telescopic
cylinders are used
in a variety of industries, such as agriculture, construction and machinery
manufacturing.
Hydraulic cylinders are often used as part of a larger hydraulic system that includes pumps, valves and motors.
Hydraulics can be effectively combined with other technologies through
the use of sensors, transducers and microprocessors. Hydraulic cylinder distributors work with many industrial equipment applications, including bulldozers, aerial lifts, weapon systems, drilling rigs, forklift
trucks, farming and demolition equipment, etc. When ordering hydraulic
cylinders, it is important to know the bore, stroke and rod sizes, the retracted pin center, the pressure requirements
for the extending and retracting of the piston rod and the flow rate
of the hydraulic fluid. Other necessary pieces of information concerning
hydraulic cylinders include rod material, operating temperature range
and coating.

Types of Hydraulic Cylinders
Double-acting cylinders
use hydraulic pressure to actuate the rod to extend and retract in both
directions.
Heavy duty cylinders
are designed for high pressures, high flows and rugged environments.
Heavy duty cylinders are particularly suited to demanding industrial
and mobile applications.
High pressure hydraulic
cylinders 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.
Large bore cylinders
are designed for a multitude of applications in which a large force
is required in both the push and pull directions.
Mobile hydraulic cylinders
are used in many applications, such as snowplows, construction equipment,
personnel lifts and material handling equipment.
Single-acting cylinders
use hydraulic pressure to actuate the rod in only one direction.
Small hydraulic cylinders can have strokes of less than an inch and are used in applications that require extreme precision.
Stepped cylinders
are two-way hydraulic cylinders that provide a faster starting stroke
and a subsequent, more powerful working stroke.
Telescopic cylinders
have multiple stages which enable longer strokes to be achieved, while
utilizing less space.
Thread cap cylinders
have their head gland threaded on and the threads are protected by an
o-ring.
Tie-rod cylinders
use one or more tie-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.
Welded cylinders
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.
Common Terms Related to Hydraulic Cylinders
Accumulator -
A container in which fluid is stored under pressure. Accumulators have
some type of limit in the loading mechanism for maintaining pressure.
Bleeder - Also called a bleed
valve, or a device commonly used on hydraulic cylinders to remove pressurized fluid
and air from the system.
Bore - The inside diameter of
hydraulic cylinders.
Cap - End closures of hydraulic
cylinders,
that completely covers the bore area.
Closure - Cap, plug or cover
for the fluid passage of hydraulic cylinders.
Depth Control Cylinder - An
adjustable, mechanical or hydraulic device that is used to limit the
stroke of hydraulic cylinders.
Flow Control - A device which meters
the rate of fluid used in hydraulic cylinders.
Gland - The cavity of a stuffing
box used within hydraulic cylinders.
Head - The end closure of hydraulic
cylinders
that covers the differential area between the bore area and the piston
rod area.
O-Ring - A type of seal consisting
of an elastomer in the shape of a doughnut. O-rings are usually mounted
in a groove on hydraulic cylinders for sealant purposes.
Piston - A cylindrical member
forming the internal element of assemblies in hydraulic cylinders that transmits or
receives motion by a connecting rod. Fluid acts with the piston to convert
pressure energy into linear motion within hydraulic cylinders.
Psi (Pounds Per Square Inch) - A
unit of measurement of pressure within hydraulic cylinders.
Pump - A device found within
hydraulic cylinders that turns mechanical
energy into either fixed or variable hydraulic energy.
Ram - The large output piston
of a hydraulic cylinders press.
Regenerative Circuit - A device
that directs the rod end discharge to the piston side of hydraulic
cylinders, increasing
the speed of hydraulic cylinders. Regenerative circuits can be incorporated into
a directional control valve as the fourth position on hydraulic
cylinders.
Rephasing Cylinder - A design
that allows the use of two or more hydraulic cylinders in a series. This design
automatically synchronizes the position of hydraulic cylinders at the end of every stroke
within the hydraulic cylinders.
Rod - A device that connects
the bore area to the head of hydraulic cylinders.
Spool - Any cylindrical-shaped
part of hydraulic cylinder components that controls the flow passing through the
component in accordance with its movement.
Stroke - The linear movement
of a valve spool or hydraulic cylinder rod that establishes the limits of motion.
Stuffing Box - A small chamber
in found within hydraulic cylinders that is compressed around a reciprocating shaft or piston
to form a seal.
