Looking for a Hydraulic Cylinder

What information is on that "HL" tag that is visible in the picture?

Only the info i already said.

Have you exhausted the OEM parts approach?

This appears to be a link for factory replacement parts.

Yes, they are saying i need the paperwork that has the serial number or model number, which i do not have. They contacted Hydro-line/Eaton and they said the same thing.

Maybe a silly question but have you contacted Hydro-Line/Eaton yourself? Asked to talk to someone in engineering?

I only ask because that seems like the best source.

I have found while on searches like this (and there have been many), the OEM reps will not push as hard for my cause as I will to get answers.

Just a suggestion

Thanks for posting the second picture - wish I could have been of more help

I could be wrong but just going by the type of fittings and lines connected to it I would be inclined to think its a pneumatic cylinder with a 1.5 inch bore and 2 inch stroke which should be pretty common to find a replacement for.

I'm inclined to think the same... Pneumatic 1.5"bore 2" stroke... but the question is:

• what are the mounts?
• geometry of the body?
• does it have cushioning?
• port sizes/types?
• rod size?
• pressure rating?

Do you know any of this information?

In a worst case scenario, you can take the old one to a competent machine shop and have them make you an exact replica. I've done it. It's not cheap, but you will have a new cylinder.

The appearance of the hoses and fittings, plus the size of the cylinder ends, suggests hydraulic rather than pneumatic. Bore 1.5 x stroke 2.0 also makes sense, and cushioning would be unlikely on such a short stroke. Some overall dimensions would help, even if the bore remains uncertain. The stroke can be measured by how near/far the rod extends. If there is a gauge in the system, we would also know the pressure.

The actual hoses look like pneumatic to me as they are not braided, but look rather like plastic lines... but... a system pressure range would surely tell us what it is.

On taking another look, I agree that this is more likely pneumatic, despite the heavy appearance of the cylinder. Thanks!

Would you call your line of pneumo cylinders "HYDRO-LINE"? Just askin...

It is starting to appear that we will never find out.

Considering Hydro-Line is a division of Eaton, where the Hydro-line encompasses both Pneumatic, and Hydraulic cylinders, I would say it surely is possible.

The above link is the datasheet/manual for Eaton's Hydro-line cylinder series, from which The cylinder in question can be identified.

There it is, plain as day. Hydro-Line pneumo cylinders.

Info on the 'net about the original manufacturer is limited. It appears that Hydro-Line was a trademark belonging to Spotton when it was manufactured, but no longer...

I'm getting a headache. You guys are doing fine, I'll leave you alone.

These people seem to have cylinders that would match the information you have so far. But, we do not know the fine details of yours. There could be 20 feet of cylinder rod to the right of the picture. In the world of manufacturing, cost is a big factor in selling the item. If Arpco could use a standard hydraulic for their Slitter Rewinder, they would not pay to have a custom cylinder manufactured. Try removing it and contacting a local hydraulic repair facility near you. Usually they can be rebuilt easily enough. Is yours giving you any problem other than leaking?

Looking at the hoses( Nylon type push fit of some sort.), i think personally its an air cylinder, i agree with the bore being 1.5" and stroke 2". Fixed base it looks like, which would see strange unless is is pushing on another shaft directly. thereby it would possibly have just a common eye bored through the rod end.

Hi QualityKaty,

Try www.Spotton.com They are Canadian hydraulic cylinder manufacturers.

Your right about needing more information, I sold Hydro Line cylinders many years ago and the details you have are only the start of a long series of numbers and letters specifying the threads, seal materials, port size and position etc. etc.

Hope the web site is of help.

Best regards,

John

Um, can I ask what seems obvious to me? Since you have the cylinder in hand, you can measure the rod end threads and the port sizes. Same for the physical configuration....look at it amd start measuring and noting things like mounting hole locations, spacings and sizes. If you set up a simple bench test with low air pressure, you can verify the stroke length.

Lastly, if you are planning on replacing the cylinder, take it apart and see what's inside. That will verify cylinder bore and whether end cusions are present.

Is everybody seriously saying that without a full part number you can't decipher what you have in your hand?

try surplus center. they have all kinds of cylinders

I work for Mark Andy which now own the Arpeco liine. The Mark Andy part number is AR-S25002. Call Mark Andy parts. We have a couple of these in stock.

Do you need to replace completely or just a seal kit, or rod end - typically servicing is a better option - for this Authorized Service Centres are a good option.

There are dozens of features which can be customized on OEM (Spec'd) cylinders (Cushions, orificing, seals) that can affect your very expensive web printer - Unless you can tear the cylinder apart, I wouldn't be looking to save a few buck from the local mom 'n pop shop - use OEM parts

Looks like a N.F.P.A. cylinder which are interchangeable. If you have a local company you deal with that sells cylinders call them. The salesman will happily match it up for the sale. Lot of the time the manufacture leave the model designation off. It does look like a Spotton model C. There is usually a serial number too. Small numbers stamped in the plate. Unless by request the were left off by the OEM.

After reviewing all of the really great responses from you guys, it looks like I'm going to have to send it in to have it custom made. As for buying it direct from Mark Andy, that unfortunately is not an option for me, but thank you for the part number.

Thank you for all of the your help!!
