We specialize in hydraulic cylinders and cylinder components.

Currently, we manufacture cylinders and Components with the technical specifications of our standard package, which comprises well-thought-out series of single and double-acting hydraulic cylinders with pressure levels varying from 2500 Psi to 5000 Psi and bores from 1.5’’ to 10”. The maximum stroke length is 20 feet. In addition to the standard series, we also offer a metric version of cylinders and which designed according to the ISO9001:2008 standard. The cylinders in this series have an operating pressure of 3000 Psi and bores starting from 40mm to 400mm and stroke length up to 6 meter.

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.

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.

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.

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.

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.

Force is determined by multiplying the area of the piston by the pressure (PSI). (r2 x p x PSI)

No. Unfortunately, exact shipping charges are determined when the order is shipped. You can preview shipping estimates during the checkout process. These charges are estimates only.

SEA HYDRO is supported by a team of dedicated and experienced hydraulic design engineers with years of knowledge in the working of hydraulic cylinders.
