Thread: What is this?

So I've had this (what seems to be) hydraulic ram for a couple years. Got it for $20 and figured if no good then maybe able to use the parts.

Anyway, got around to taking it apart and was surprised at what I found.

The actual piston is all steel and undersized.

To give you an idea, the bore is 60.00mm and the piston is 57.75mm approx.

No seals and seemingly nowhere to attach a seal.

This ram has a port in the base as per usual and had a hydraulic hose attached, I threw it out as it was damaged.

Cant work out what is does or what its used for.

Couple things;

Is it missing a piston seal. If so, how does it attach?

Is it some type of hydraulic damper? But it still would have a sloppy fit with metal on metal.

Any help much appreciated!

Its a displacement cylinder:

Thanks for the link.. That makes a lot more sense now.

Fitted to a lot of old tractor front end loaders.

So, i assume with a small amount of handiwork i could convert to a standard single acting hydraulic ram?

with absolutely 0 work it can be a single acting hydraulic cylinder

I know very little about hydraulic rams.
How is it that it can have no seal?

Read the link in post #2

That ram is very similar to the rams on my Horndraulic Loader that is fitted to my Nuffield tractor - single acting as someone else mentioned. I'm sure that it could be used for a multitude of projects, even a long range hydraulic press with suitable springs to retract the ram.
