Hydraulic Cylinders are actuators used in both large and small scale industries, in manual and Auto tools. They give a leverage of force to move a workload. Hydraulic cylinders are used in machines that push, pull, lift, steer, clamp or ease down heavy loads. They are used in the automotive industry, civil engineering, mining, drilling, warehousing, shipping and marine industries.
Cost
When the SS body disposable cylinder was developed, many people questioned the viability of a non-repairable product. This product has not only succeeded, it has also revolutionized the market. Because of its low cost and ease of replacement, many organizations opted to replace many traditional steel, aluminum and brass body cylinders that could be repaired. While these pneumatic cylinders are the most cost-effective choice and easiest to use, they do have limitations that make them less-than-ideal for certain applications.
Bore
The first essential information to take into account when choosing the size of the bore is the operating pressure.
Knowing the operating pressure you want to use will help you choose the size of the cylinder bore.
The second key information needed to choose the size of the bore is the amount of force required for the application. Here is a quick formula to find the approximate size of the bore in the direction of cylinder extension :
F = required force (N)
P = operating pressure (bar)
A = Surface of the bore (mm²)
D = bore diameter (mm)
D = √4.F / √π.√p
As a general rule, the resulting bore diameter is rounded to the next standard bore size.
Rod Size
Once a minimum cylinder bore size finalized for the Load the next major step is to choose the appropriate rod size. Selecting the required rod size and the Stroke length requires careful consideration as it may affect the rod buckling strength. At SEA HYDROSYSTEMS we use programs that calculate whether rod buckling strength for a given rod size and stroke will be suitable for a given load. If you need assistance with this or need a more customized hydraulic selection guide, simply contact us.
Some application demands the design of a custom made a hydraulic cylinder. Look no further you’re in the right place, we support custom cylinders with our one of the best design team around.
In general a Hydraulic press cylinder Piston rod will need to be 2/3Rd Of the Bore size. For machine tool applications the ratio will be 1/2 the size of Bore.
Consider the Mount
Cylinder mounts can be divided into two basic categories: pivoted and straight line. Selecting the right mount for an application mainly depends on the desired movement of the load. Pivoted mounts can be used where a load needs to move through an arc and include mounts such as Trunnion and clevis.
In comparison to pivoted mounts, straight line mounts are used when the load only needs to move in a linear direction and include mounts such as front head flange and side lug. It is necessary to consider the desired movement of the load specific to your application to ultimately determine the type of mount.

When choosing a Air Control Valve for a process, there are many things that must be considered, including the valve’s flow characteristic, its size, noise, the potential for cavitation or flashing damage, body and trim materials, actuator size and type, and its dynamic response to changes in the control signal.
The selection primarily depends upon the application and the pressure and temperature conditions.
Media
The first and most obvious question is—what gas (or liquid) will be controlled by this valve, and at what input pressure? Compressed Air? Water? Negative Pressure? Gas? Before checking for any additional factors, ensure that the valve is compatible with the media and pressure passing through.
Method of Valve Actuation
There are a variety of methods available to open or close a valve. The four most common are Solenoid operated (via electrical current), Manually operated (by skilled labor and via a lever, pushbutton, foot peddle, etc.), Mechanically operated (via tooling or work pieces in contact with a cam, ball or plunger), or Remote Air operated (from an output signal of another valve).
Spring-Return or Detented Actuation
This is the return method the valve will take “back” to its original, un-actuated state. Typically, this is either a mechanical spring, or a separate form of the same actuation method described above. Manufacturers call these methods “spring return” and “detented” valve types. Said another way, are you looking for a “momentary contact, momentary output” or “momentary contact, maintained output”? Decide whether you want your valve to return to its initial position or stay in its last position after actuation.
Valve Configuration
Most pneumatic directional control valves are 2-way, 3-Way or 4-Way and, as a rule of thumb, it is a count of their active media ports.
2-Way valves have one INLET and one OUTLET port and, upon actuation, allow media to pass through (known as a 2-way Normally Closed), or to stop flow (2-way Normally Open)
3-Way valves add a third port to allow for venting (EXHAUST port) of pressure at the OUTLET port, when the INLET port is blocked. 3-Way valves are offered Normally Closed or Normally Open, as well.
4-Way valves add a second OUTLET and corresponding second EXHAUST port to the 3-Way function, and are most commonly used for control of double acting pneumatic cylinders and actuators. Upon 4-Way Valve actuation, INLET pressure switches from one OUTLET port to the other.
Note: As an option, 4-way valves can be configured with 3 positions, where the center position is forms a “neutral” position choice of three options (either all OUTLET ports exhausted, pressurized, or checked).
Flow Capacity (Valve Size)
Flow capacity is a fifth factor to address in valve selection. An undersized valve will slow down fill time or cause other forms of inefficiency in the system while an oversized valve can be classified as a form of waste in the system. It’s important to estimate a maximum flow capacity for your application and select the valve size with enough capacity. All valve suppliers provide a flow capacity, and have easy reference material to assist you, but essentially your valve will need to fill a specific downstream volume within your acceptable period of time.
In addition to the above-discussed tips, you can discuss your requirements with the manufacturer.
