Tips for Choosing a Hydraulic Cylinder
There are several factors to consider when selecting a cylinder:
- Bore diameter (the inner diameter measurement of the cylinder bore) which determines how much force can be developed at a given oil pressure
- Required stroke of the cylinder (how far the rod extends)
- Piston rod diameter, which is crucial since it force must be applied without bending or buckling
- Required speed because it will determine the gallons per minute needed from the pump as well as the correct inlet and outlet port sizes.
- How the cylinder will mount, whether through an arc or in a linear direction
- Where and how the cylinder will be used in order to determine the appropriate materials, seals, and finishes
Why Hydraulic Cylinders Fail
You will want to keep your hydraulic cylinders from failing when you need them most. Here are the most common causes of cylinder failure:
- Contaminated oil – Contaminated oil is the most common cause of hydraulic cylinder failure. Foreign particles in the oil can scratch and score the interior of the cylinder and eat away at critical seals and fittings. Help ensure that clean oil is entering the cylinder by installing high-efficiency filters. Checking the filter regularly will help prevent clogging and keep debris from getting to the inside of the cylinder.
- Overheated cylinder – A hot cylinder can prevent the system from operating effectively, accelerate oil degradation, crack seal compounds, and waste electricity.
- Damaged/bent piston rods or rod bearings – This problem is often caused by overloading the cylinder or by misalignment of the load and the cylinder. Rough places on the rod can damage the seals, reduce their normal life, and cause you to replace them more often than necessary.
- Broken eye bearing – The eye bearing can break if the cylinder is forced to handle a heavier load than it was designed for or by a sudden impact caused by high pressure.
- Seal leakage – The most common reason for this is an improperly fitted seal. However, corrosion or abrasion of the cylinder seal grooves, oil contamination or entrapment, and incorrect metalwork clearances are a few of the other reasons that seals may leak.
- Excessive moisture – Exposure to heavy moisture, either ambient or within the fluid, can lead to damage of the seal, rod corrosion, and failure of your entire hydraulic system. In some cases, a corroded and damaged rod can be re-chromed or polished to refinish it.
