The Meanings of Hydraulic Cylinders Codes and Model Numbers

The code and model number tells its type and size, which is important for ordering parts or giving to a repair shop.

Let’s say you had a single acting telescopic cylinder, you would need to know what you had in order for a repair shop to fix your cylinder. They may have to order parts to fix it. No different when you go to a tire shop, they need to know the size of the tire in order to replace the one you have on there. Dealers and suppliers (such as ourselves) will need to that in order to fix your cylinder and get you back at the job at hand.

This is an example only

Let’s say this is a S94CC-1-302

S = Single Acting type

9 = 8 1/2″ nomianl O. D. of largest sleeve

4 = 4 stages or sleeves

C = Mounting on base end

C = Mounting on rod end

-1 = Modification or desing variation

-302 = 302″ stroke

So always keep up with those model numbers, part number and serial numbers. It will make things alot better when ordering parts or working with a repair shop.

  1. Oh, no! One of the hydraulic pumps at my local workshop has stopped functioning all of sudden yesterday. Speaking of which, it was really nice of you to talk about the mounting of our hydraulic cylinder which has to be taken into consideration when repairing it to ensure a long-lasting result. I’ll show this article to the owner so he could seek the right assistance sooner or later to fix the issue.

  2. It’s good to know that the model number is crucial when ordering replacement parts for a hydraulic cylinder. The hydraulic cylinder in my work truck has been acting up over the past two weeks, and I’m not sure how to fix it. I’ll have to reach out to a repair shop to see what the issue is.

    1. Well you have to get the right seals in it to repack it. Something may be wrong with your rod also. Don’t know where you live, We are located in Tupelo MS. If your close bring it in. If not, yes you would have to take it to a repair shop.
