1, what is called single acting cylinders?

Single acting hydraulic cylinders are idea for used in applications that have weight gravity or another assisting force which will move the cylinder in a single direction.

Single acting hydraulic cylinders use hydraulic pressure to extrend or retract the rod in one direction.

Single acting cylinders often cost less than double acting cylinders and work good in a vast range of mobile and industrial applications.

2, what is called double acting cylinders ?

Double acting cylinders are more common than single acting cylinders. Because they work in more applications at almost any angle

3,  what is called a piggywork cylinder ?

Piggyback hydraulic cylinders use 2 cylinders in opposite directions that are yoked or welded together.

This means that there is twice the stroke while taking up half the space.

Piggyback cylinders are idea in applications that have limited space but require a long stroke.

4, what is called a telescopic hydraulic cylinder ?

Telescopic hydraulic cylinders are made available in single acting and double acting types.

Like piggyback cylinders they allow for a long stroke while taking up much less space when collapsed.

5, what size of a hydraulic cylinder should i choose ?

Usually it depends on how much psi of hydraulic pressure you need or how many stroke you require.

For example: (mm)

If bore 80  rod 50. close length is 1615 or so.

If bore 120  rod 85.  close length is  3020  or so.

If bore 200  rod 140.  close length is 3600  or so.
