HOW THE HYDRAULIC CYLINDER CLASSIFIED BASED ON ITS FUNCTION?

Single Acting Cylinders:

In single acting cylinders the fluid is pressurized from only one side of the cylinder during both the expansion as well as the retraction process. A spring or an external load is used to return the cylinder top to its original position i.e. when pressure of the fluid is cut off.

Double Acting Cylinders

In the double acting cylinders, the pressure from the fluid is applied in both the directions. Single cylinders that consist of springs are not used in large stroke applications because there are inherent mechanical problems associated with the spring. The double acting rods could be of two types

•  Single rod ended

•  Double rod ended
