FAQ：

1.What kind of products do you sell?

We specialize in hydraulic cylinders and cylinder components.

2.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.

3.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.

4.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.

5.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.

6.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.

7.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)

8.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.

9.Do you Provide technical Assistance?

Huaheng company is supported by a team of dedicated and experienced hydraulic

design engineers with years of knowledge in the working of hydraulic cylinders.
