A cylinder is a device that converts fluid power into linear mechanical force and motion. A hydraulic cylinder is a linear actuator used for converting fluid energy to an output force in a linear direction for performing various jobs.

Classification of Hydraulic Cylinders According To 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.

Some of the special hydraulic cylinders we are familiar with are;

HIGH TONNAGE CYLINDERS:High Tonnage cylinders can create huge tonnage force.These are specially used in heavy engineering machinery's.Theseclinders can create either be single acting or double acting.

1. Cylinder Tonnage: 0.5T TO 5000T.

2. Working pressure: up to 350 Bar.

3. Stroke: Up to 5000mm.

4. Type: Single acting & Double acting.
