High quality CE certified single double acting hydraulic welded cylinders for press machine

We can make according to the customer's drawings and requirements. Please send us your drawings or sample sizes, or tell us your requirements. Our r&d department will design for you. We can design according to user requirements, manufacturing hydraulic cylinder.

Product Description

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 application.

*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 immediately
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 cylinder?
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 retracting.

*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 barrel,
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 on the
cylinder retracts the rod. The diameter of the rod is the effective piston area.

*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.
