Types of Hydraulic Cylinders
In hydraulic cylinders, we can categorize two functional types such as “double acting” and “single acting” cylinders. Only rapid traverse cylinders and telescopic cylinders could be segregated as “double acting and “single acting” cylinders. According to the function, we can sort hydraulic cylinders in the following manner.
- Push-action cylinders
- Telescopic cylinders
- Rapid traverse cylinders
- Pull-action cylinders
- Differential cylinders
- Tandem cylinders
- Double rod cylinders
- Rapid traverse cylinders
- Telescopic cylinders
Single acting cylinders have one effective area, on the bottom side, which can exert force only in single direction. In most hydraulic systems, these are typically designed as plunger cylinders. So that an alternative force is required to send back the piston to the starting position: e.g. lifting devices, upstroke presses, etc. In absence of such force, a set of effective springs must be placed.
Such remedy is possible only with small cylinders, simply because of the limited force and stroke length of the return springs.
Telescopic cylinders are widely used in hydraulic lifting purposes, or where large amplitudes are essential in a little operating space. e.g. tipper trucks. The single acting or double acting differential cylinder is commonly used in industrial and mobile hydraulic systems. The most common design concepts of the hydraulic differential cylinder in mill type and tie rod type are discussed below.
Consider following factors before buying a hydraulic cylinder tube cross
First you must find the weight you wish to move. Then consider the effect that the mass will put on the force required to move it. The capacity of the cylinder should always be higher than aforesaid force, which will satisfy a margin of error as well.
Once you recognize the figure (value) of the mass to be moved, you then have to think about the mathematics connected when moving it. For a machine like a press that moves up and down, the geometry is easy and needs no additional thinking. However, the force required by the cylinder changes when the centre of the load to be moved is not focused on the point of lift force and at perpendicular angles to that point of lift force. For instance, if you got a crane, the cylinder pushes on the boom usually off from the load.
After calculating the force needed by the cylinder, the next step is to determine the size of the bore required for the cylinder. The amount of force generated by the cylinder is the product of the system pressure multiplied by the area of the internal piston surface (upon which that pressure acts). This formula is used to calculate the bore size needed to achieve the calculated force.
When the minimum cylinder bore size is calculated, next step is to select the tube cross of the hydraulic cylinder, in order to determine the corresponding rod size. Selecting the required rod size calls for careful consideration of the stroke length needed which affects the rod buckling strength.
Consider the Mount
There are two basic categories of cylinder mounts are available: straight line and pivoted mounts. Selecting the correct mount depends on the desired movement of the load. Pivoted mounts can be used where a load needs to be moved through an arc while a straight line mounts are best when the load needs to move in a linear direction.
Knowing what would be the environment that the cylinder is going to operate in is also crucial in selecting the appropriate seals, materials, and finishes. Specially, the material of the cylinder should be changed to meet specific environmental conditions.

Tips for using hydraulic cylinder tube cross
- Inspect every component before you set up your hydraulic cylinder system. Never use damaged or worn out parts.
- Read all instructions and warning labels. Operating instructions must be understood before using the cylinder.
- Only fill the pump to recommended level; only fill it when connected cylinder is fully retracted.
- Avoid exposing the cylinder to extreme heat or weld splatter
- Always check the specific mounting, and bore sizes to be sure it hasn’t been de-rated in pressure.
- Be aware of the environmental conditions the cylinder will be exposed to. Although the cylinder may be compatible with the operating fluid, external fluid may degrade the rod seal
- Make sure you don’t ignore the linear velocity of the cylinder. It may be advisable to use a proportional valve or even an external shock absorber to handle excessive deceleration or to absorb kinetic energy.
- You should be aware of the type of internal piston sealing method used in the cylinder you’ve specified.
1. What is the difference between single-acting and double-acting cylinders?
A Single acting hydraulic cylinder will only extend by pressure from a pump and then retract by the weight of the load or by an internal spring. A Double acting hydraulic cylinder, on the other hand, employs the use of hydraulic power to both extend and retract. An easy way to differentiate the cylinders is to look at the number of ports. A Single acting cylinder will have only one port for the connection of a hydraulic hose. A double acting hydraulic cylinder tube cross will have two ports.
2. What are some common causes of cylinder failure?
-Side loading – Side loading is caused by the cylinder being misaligned which creates an unusual force on the piston rod.
-Contaminated Fluid – Contaminated fluid can cause premature rod seal failure
-Rough or scored rod – Rough places on the rod damage the seals and reduce their normal life resulting in the necessity for frequent replacement.
3. How does a hydraulic cylinder tube cross work?
The principle behind hydraulic cylinders is that force applied at one point is transferred to another point using an in-compressible fluid. The hydraulic fluid is actually some oil. A fairly easy hydraulic system includes two pistons connected by a pipe loaded with oil. As a force is applied to one piston, it is actually transmitted to the second piston via the oil in the pipe. Oil is in-compressible and, thus, is a very efficient medium for the force to go through; nearly all force given to the first piston appears in the second.
4. How do I measure a cylinder?
Look at the pin to pin length if the cylinder is fully retracted and fully extended, measure the diameter of the rod, the bore of the cylinder will typically measure 0.25 inches-0.5 inches less than the outer diameter from the barrel, also determine what type and size of the ports. Then finally, determine the type and size of the end mounts.
To sum it up, a hydraulic cylinder tube cross is an useful gizmo to use in construction equipment, manufacturing machinery, agricultural industry and civil engineering. There are plenty of models of hydraulic cylinders in the industry and before selecting you must evaluate your budget, the mass you would like to lift, the geometry, the bore size, the rod size and the tube cross mount to ensure that you get the right stuff for your particular application. To make sure the longevity of the hydraulic cylinder along with the safety of the operator, stick to the maintenance procedures provided by the manufacturer. Always replace or repair worn- out or damaged cylinders. Hopefully this article gave you all the essential information that you need in order to make a decision on which hydraulic cylinder to order.
