What is the difference between double acting and single acting?

Differences in how they work

The plunger in a single-acting hydraulic cylinder extends when hydraulic fluid under high pressure is pumped into the cylinder. When it is time to retract the cylinder, depending upon the cylinder design, the plunger can be retracted using a return spring, by the load, or simply by gravity.

In a double-acting hydraulic cylinder, the plunger retracts when hydraulic fluid is pumped under high pressure into the top port, forcing the plunger back to its original position. This can be done quickly, if required, or very gradually with precise control.

Different advantages

Single-Acting Hydraulic Cylinders VS Double Acting Hydraulic Cylinders

The single-acting hydraulic cylinders is simpler than its double-acting counterpart. With fewer components, there is much less to go wrong, which is good news when it comes to maintenance. Single-acting cylinders are ideal for straightforward jobs – especially when fast or controlled retraction isn’t essential. 

Double acting hydraulic cylinders have the ability to pump hydraulic fluid to both sides of the plunger. Connection ports positioned near both ends allow the piston rod to move both forwards and backwards. The extra port also allows more control of the plunger during retraction and ensures it always returns back to its starting point. The faster and predictable retraction of double-acting cylinders makes them the better choice for projects needing repeatable accuracy.
