Identify a seal

[KimB]

Hi guys, I have this seal from a hydraulic ram that I’m struggling to identify/match up. The sizes are on it but can’t find a replacement?

Any ideas. Also not sure what type of seal it’s called. Is a Y type?

This is the first time I tried to sort a ram seal.
Thanks

Looks a regular lip seal,try SEALMASTERS,Cardiff,02920490711, yes just noticed a taper.

No. Yes. So what.

Seals are dimensioned and made so that when installed in the groove in which they reside, they do the job they are supposed to do. When free of that groove, it is entirely possible their natural elasticity may cause them to assume a different shape.

Hi Kim, if you get no joy on here, a mate of mine had a press repair company, I will forward the photos to him, I’m sure he will recognise it.

Edit, I’ve just sent the photos to him, will see what he says.

Looks like a cup (pressure) seal not a wiper/oil seal.

FPE Seals are the hydraulic industry supplier

strange reply? , most are parallel on the outside even when removed its unusual to see one that goes tapered out side thats all ,as most are on a steel rim that holds the shape , I think we all know how seals fit and work ,obviously there is good reason why its outside is tapered ,well hopefully anyways , either way hope @KimB gets one found.

That would be an axle or shaft seal with the steel outer band.
This being from a Hydraulic cylinder, is a different animal.
I defer to the counter people at the seal vendor, they know these things very well.
There are rod end seals, piston seals, back up rings, square cut, round, quad, many different styles etc. it is a real can of worms.

I too would be finding a local supplier, even on the end of the phone/email.

A u seal or u cup is a standard hydraulic cylinder seal fitted in single acting rams. Here are two examples from jacks I repaired recently both are tapered in section, but having slightly different features.

No steel rims in sight

That's a ram seal by the look of it, most seal company's don't stock ram seals just rotary seals for shafts, as Brad said try fpeseals.com. I think they're called U ring seals?

steel rim in" normal" seal is covered in rubber , but that taper makes sence in a hydraulic seal , appreciated

Have always called them Cup seals, as long as you have the I/D, O/D & depth of where the seal needs to go you should be able to find a replacement.

Kim, I’ve taken umpteen rams, of all types, for repair. Look up an agricultural repair workshop and ask where the most local reliable repairer is to be located (if they can’t identify it).

 

[Cobbler]

@KimB I’ve passed on the photos to my mate & he’s come back & said it looks like a rubber/fabric “U” seal. If you can’t source one, come back to me, as he may be able to help.

 

[KimB]

Thanks for all the advice guys. I’ve asked someone and see tomorrow if I get any response or luck. I’d say you’re right the it’s a U seal.

Also as a point of reference the 28mm is the ID but I’m not sure what the 33 is meant to mean next to it? Maybe that’s what it’ll stretch to?
The 48mm is the od

And it’s 10mm thick but I don’t know what the 5 denotes?

it may be it can got to a 33mm shaft as a max?

here is an option for a 28x48x10 cup seal for hydraulics
