What is the difference between double acting and single acting cylinders?

What is the difference between double acting and single acting cylinders?

Double-Acting – have a port at each end, supplied with hydraulic fluid for both the retraction and extension.

Single-Acting – hydraulic fluid enters through a port at one end of the cylinder, which extends the rod by means of area difference. An external force or gravity returns the piston rod.
