1. What cylinder do I need for my hydraulic system?
First, do you need a single or double acting cylinder?
Next, what is the pin to pin distance when extended and retracted.
Also, how much force do you need to move the load, do you need it to move in a certain amount of time
and how is the cylinder mounted.
 
2. What's the difference between a single and a double acting cylinder?
A single acting cylinder only provides force one way (most snow plow and telescopic cylinders are single acting).
A double acting cylinder provides force when extending and retracting.
 
3. How do I measure a cylinder?
Measure the pin to pin length when the cylinder is fully extended and fully retracted, measure the diameter of the rod, the bore of the cylinder will typically measure 1/4" - 1/2" less than the outer diameter of the barrel, also determine the type and size of the ports. Finally, determine the type and size of the end mounts.
