A hydraulic cylinder is a mechanical actuator (a type of motor responsible for moving a system) that gives unidirectional force from a unidirectional stroke. It is applied in construction equipment, manufacturing machinery, and civil engineering. Hydraulic cylinders are classified into two categories depending on their functions and structure: single acting and double acting cylinders.
There are many hydraulic cylinders in the market, and this guide is aimed at making your work easier when you want to buy a hydraulic cylinder tube cross or clevis end by giving you all the necessary information. On top of that, we have reviewed seven hydraulic cylinders we think are worth your money.

Factors to consider before buying a hydraulic cylinder tube cross
You must find the amount of weight you wish to move and once the mass is known you must then consider the effect that the mass will have on the force required to move it.The force of the cylinder should always be high enough to allow for a margin of error.
Once you recognize the character of the mass being moved you then have to be compelled to think about the mathematics concerned with moving it. For a machine like a press, which moves up and down, the geometry is easy and needs no additional thought. However, once the center of the load being moved isn’t focused on the point of lift force and at perpendicular angles to that point of lift force, the force required by the cylinder changes. If you’ve got a crane, for instance, the cylinder pushes on the boom usually terribly off from the load.
- Bore size
Once you calculate the force needed by your cylinder, the next step is to determine the bore size required of the cylinder. The force generated by the cylinder is simply 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 that force.
- Rod Size
Once a minimum cylinder bore size is calculated, the next step to the selection of a hydraulic cylinder tube cross is to determine the appropriate 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
Cylinder mounts are divided into two basic categories: pivoted and straight line mounts. Selecting the correct mount for an application depends on the desired movement of the load. Pivoted mounts can be used where a load needs to be moved through an arc.Straight line mounts are required when the load needs to move in a linear direction.
- Environmental Conditions
Knowing the environment the cylinder is going to operate in is crucial in selecting the appropriate materials, seals, and finishes. The material of the cylinder can be changed to meet specific environmental conditions.
Do we actually know how this cylinders works on such loads? I think this industrial video that describe the manufacture methods on a hydraulic cylinder will give us a great idea (Also it could help and influence the purchase decisions a lot.)

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 basic idea behind hydraulic cylinders is that force applied at one point is transferred to another point using an in-compressible fluid. The hydraulic fluid is usually some oil. A simple hydraulic system consists of two pistons connected by a pipe filled with oil. As a force is applied to one piston, it is transmitted to the second piston through the oil in the pipe. Oil is in-compressible and, therefore, is a very efficient medium for the force to travel through; almost all the force applied to the first piston appears in the second.
4. 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 0.25 inches–0.5 inches 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 summary, a hydraulic cylinder tube cross is a useful tool for use in construction equipment, agricultural industry, manufacturing machinery, and civil engineering. There are many models of hydraulic cylinders in the market and before buying you should consider your budget, the mass you want to lift, the bore size, the geometry, the rod size and the hydraulic cylinder tube cross mount to make sure you get the right equipment for your particular application. To ensure the durability of the hydraulic cylinder and the safety of the operator, follow the maintenance procedures provided.Make sure to replace or repair worn- out or damaged cylinders. We hope this guide gave you all the necessary information that you need before making a decision on which hydraulic cylinder to buy.
