What are hydraulic cylinders?

Hydraulic cylinders are specially engineered systems that can transform hydraulic fluid energy into power and use this power to generate linear movement. They are like the pneumatic cylinders but differ as a pneumatic cylinder uses air and a hydraulic cylinder uses fluids. 

A hydraulic cylinder consists of a steel tube and has a piston with a rod protruding from one side as well as mounting attachments. 

Importance of hydraulic cylinders

Capable of generating linear mechanical movements, hydraulic cylinders are widely used to lift, push, and press objects, alongside other tasks. A common example of using a hydraulic cylinder is when your car mechanic elevates your car on a lift to check or work underneath. 

Best practices while buying hydraulic cylinders

Choosing the right hydraulic cylinder is extremely important. But for doing so, you need to consider different factors, such as:

Bore Size:

One of the most important steps toward choosing the right hydraulic cylinder is determining its bore size. It will enable you to determine the force of the cylinder as well and help you to make a choice that is effective for you. To determine the bore size of the hydraulic cylinder, you can use this simple formula:

F = forces required (lbs.)
P = operating pressure (psi.)
D = bore diameter (in.)

D = F / (Pi/4* P)

Rod Size:

After you have determined the bore size of the hydraulic cylinder, you need to identify and select the appropriate rod size. The rod size can affect the rod buckling strength, further impacting the load suitability. In short, if you choose the wrong size, then it can lead to load failures. 

Cylinder Mounting:

Hydraulic cylinders are available in two types of mounting capabilities – pivot mounting and straight line mounting. Depending on your application, your preference for cylinder mounting can change. For example, if you want a cylinder where the load moves through an arc, then you can go for pivot mounting. And if your loads require linear movements only, then straight line mounting is recommended.
