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. The force is almost always multiplied in the process. The first and most critical step is to determine the Cylinder Operating Pressure, The basic operating pressures that are commonly used range from psi to psi.
A quick formula for finding the approximate bore size for the extending direction of the cylinder is as follows:. 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. 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.
Pivot m ounting can be used where a load needs to move through an arc and include mounting such as Trunnion and clevis. Straight line mounts are used when the load only needs to move in a linear direction and include mounting such as rear or front head flange and Foot mounting. Hydraulic Seals play major role in operating cylinder flawlessly by preventing oil leakages.
So, choosing the right Seals are very important by considering the applications, operating environment and the maximum operating pressure. If you still require additional assistance in the selection of hydraulic cylinders, we would be happy to assist you.Hydraulic Hose - How To Make an Assembly
Hydraulic Cylinder Seals, O-Rings : Hydraulic Seals play major role in operating cylinder flawlessly by preventing oil leakages. U-Cup seals, step seals are some common ones.
Wiper Seals or Dust seals, prevent contaminants from entering the cylinder. Besides direct wire to the rod seal, external contamination, can have disastrous consequences.
Double and single lip wipers and Metal covered wipers for heavy duty are some of the examples of the dust seals O-Rings, Prevents Oil leakages NBR with 70 Shore hardness will work in general applications.

We need to determine exactly where the hinge of the dump body is, and then measure from that point, forward to the center of the load. This is going to generally be the middle of the dump body. Be sure to take that measurement in inches. From that same hinge location, measure forward to where the cylinder connects to the dump body. This measurement will be larger than the previous, and should be in inches as well.
This is our cylinder base point. With these two numbers in hand, we just need to get the weight of the load we are lifting, and we are ready to do some calculations. Because the laws of physics work in our favor, the initial hydraulic cylinder force will be the highest. As the hydraulic cylinder extends, raising the dump body, the force will decrease as the dump body continues to rise. To get the initial force required for lifting, take the load in pounds, and multiply it by the first number distance from hinge to center of load.
Divide the new number by the distance from the hinge to the lifting point, and we now have our initial force required to lift the load. Now that we know the lifting force required, we can determine the stroke needed based on our dump body.
The multiplier is a number based on the dump angle. A normal dump angle ranges from degrees. Use the chart at the left to find the correct multiplier. Now multiply the base length in inches with the multiplier and we get the stroke. What hydraulic cylinder do I need for my dump body?Pneumatic cylinders are commonly used to convert the energy provided by a compressed air source into usable kinetic energy.

The cylinder rod extends and retracts to create a desired motion. The rod will extend and retract with a certain force, which is based on the diameter of the cylinder, and the pressure of the compressed air. This guide will teach you how to choose a cylinder of the correct size, based on your application. Determine the amount of force required, and the length of the stroke for your application. I'll use an example: we want to push a box 16" with lbs of force.
Determine the air pressure you will be using. This is the pressure you have available at the cylinder. In my example, I'll use 80psi pounds per square inch. From the area required, we will now calculate the diameter of the cylinder commonly referred to as the BORE. First take the square root of the area A, then multiply that by 1. In my example, the square root of 3. Now we multiply that by 1.
We have now sized the pneumatic cylinder to our application. We would need a cylinder with a 1. Note that cylinders are only available at specific Bore diameters, so in my example, you would order a 2" bore. If you find that you have more force than you want, you can always just turn the pressure down until you get the desired force.

These are unique fittings that are used to connect various components of a hydraulic system such as:. It helps direct and contain the flow of hydraulic fluid in a system. It also used to prevent leaks while maintaining pressure within the system. It is very common for hydraulic fittings to come in pair referred to as the male and female connector.
Male connectors, also referred to as a plug, has a solid pin or portion at the center of the conductor. Female connectors, referred to as a jack, are identified by the hole that accepts the pin or solid portion of the male connector. This has a very high resistance to heat. It is commonly used in industrial and commercial applications. This type of fitting has a high corrosion resistance but low tensile strength.
It is commonly used for plumbing and is often alloyed with silicon, copper, manganese, zinc and other materials to improve its strength and durability.

Hydraulic Cylinder Calculations
Make Shortcut to Home Screen?What is hydraulic cylinder? The hydraulic cylinder is a device that converts the energy of fluid into mechanical energy. The fluid is pumped into the cylinder by means of a pump and it can be used to move a load.
The size of the cylinder determines the amount of load that can be handled by it. Major parts of a hydraulic cylinder. In this tutorial we will discuss how to do the design or sizing calculation for piston.
Cylinder design will be explained elsewhere. Design calculations for hydraulic piston. The calculation of size of the hydraulic cylinder consists of two steps:. Step 1 : calculation of the area of cross section of the piston. Where, A is the area of cross section of the piston. F is the force acting on the piston. P is the pressure of fluid supplied by the pump.
Step 2: calculation of diameter of the piston. Where, D is the diameter of the piston. A is the area of cross section of the piston. Find out the required piston size. Step 1: First find the area of cross section required:.
Step 2: Calculate the piston diameter. Thus the size of the hydraulic cylinder piston size can be determined. The piston size is an important input parameter for calculating the internal diameter as well as wall thickness of the hydraulic cylinder. For the sake of simplicity we will consider the internal diameter of the cylinder is equal to the diameter of the piston for further calculation.
