Double acting hydraulic cylinder refers to a hydraulic cylinder
that can input pressure oil from both sides of the piston. It is
often used as the driving component of the jack. Double-acting
hydraulic cylinder actuators is the main output device, hydraulic
motor system while in size, type and design structure in different
ways, this part is usually the most part can be observed. These
actuators convert the liquid pressure into a fast, controllable
linear motion or force that drives the load.
A double acting cylinder alternates cycles of pressurized fluid to
both sides of the piston and creates extend and retract forces to
move the piston rod, permitting more control over the movement.
Using a control system made up of a 2-, 3-, 4- way position valve
would be required to achieve the desired movement for your
Prototype and Design Capabilities
The team at HRHD Hydraulics will work alongside you as an extension
of “your” Design and Engineering team to create a solution which is
robust, high quality, and fine-tuned for optimal performance. We
want to understand your application as well as you do!
As a full-service supplier, our team will be there for support from
start to finish and will ensure a smooth launch into production,
with dedicated ongoing support into the future.
Our sales and engineering staff will work with you to become an
extension of your team. We will be there for support from start to
finish for new or ongoing projects. We will work with you from the
early design phase and application engineering and approvals
through production and field support for the life of the product.
*What kind of products do you sell?
We specialize in hydraulic cylinders and cylinder components.
*What are your lead times for standard cylinders?
We maintain an extensive inventory of both standard hydraulic
cylinders and cylinder components and
our goal is for cylinders to be immediately available for shipment
when your order is received. Should a standard cylinder not be
immediately available, we can begin production on that cylinder
and will be able to ship that order to you within 14 working days
after confirmation of drawing.
*What cylinder do I need for my hydraulic system?
First, do you need a single or double acting cylinder?
Next, what is the pin to pin distance when extended and retracted.
Also, how much force do you need to move the load, do you need it
to move in a certain amount of time
and how is the cylinder mounted.
*What's the difference between a single and a double acting
A single acting cylinder only provides force one way (most snow
plow and telescopic cylinders are single acting).
A double acting cylinder provides force when extending and
*How do I measure a cylinder?
Measure the pin to pin length when the cylinder is fully extended
and fully retracted,
measure the diameter of the rod,the bore of the cylinder will
typically measure 1/4" - 1/2" less than the outer diameter of the
also determine the type and size of the ports.
Finally, determine the type and size of the end mounts.
*How does a displacement cylinder work?
In a displacement (single acting) cylinder the rod is extended by
flowing pressurized oil behind the rod,which forces the rod out of
the barrel like a piston. Once the pressure is released, the load
cylinder retracts the rod. The diameter of the rod is the effective
*How much force does my cylinder have?
Force is determined by multiplying the area of the piston by the
pressure (PSI).(r2 x p x PSI)
*Are shipping and handling charges included?
No. exact shipping charges are determined when the order is
shipped. You can preview shipping estimates during the
checkout process. These charges are estimates only.
