Identifying a Multicyl Cylinder

One of the most common questions we get when we talk to a customer is “How do I know what cylinder I have?” 

There are two sets of numbers stamped on a multicyl's main body.  One set of numbers is the model number, the other is the serial number

First let’s take a look at the model number. 

You can see three sets of numbers stamped into the metal beneath the oil reservoir.  This particulat cylinder is a 20 16 7.

What does this mean?

The first number is tonnage  X2

so 20/2= 10Tons@120 PSI

the second number is the total stroke in 1/8th of an inch

16/8 = 2" Total stroke

the third numer is power stroke in 1/32nds of an inch

7/32" total power stroke.

The serial number to the cylinder can be found stamped in the same area on the back of the cylinder
