Plastic washer identification

[hotponyshoes]

I've got some of these on a boat steering linkage, some kind of hard plastic/nylon type material.
Photo shows both sides of the same washer,
They have 'up' on one side and a lip on the inner diameter.

Anybody recognise them?

Any chance of a photo ?

Google ‘plastic thrust washer’

Grab a tea and sift through. Lots to pick from

I've had good results with Teflon style bread boards, and hole saws, even cutting odd size diameters using an adapted fly cutter in the mill.

It looks like a shoulder washer of some sort.

would that be the sort of thing you could 3d print ,,, or do you have a lathe and some delrin

 

[hotponyshoes]

I was hoping it would be a case of a couple of quid to buy some...
I'd think they are an off-the-shelf part somewhere...

 

[tom2207]

what size are they , they are very like the washers you get in a ballcock fitting kit

Volvo Peanta stern drive sealing ring ?

I’ve seen them before in the rose joints where the bolt goes through as spacers.

Maybe search under that but I know them as thrust washers

 

[hotponyshoes]

I'm guessing it's a "standard" thrust washer of some sort,

Actual measurements
O/D is 36.5mm
I/D is 22.3mm
Thickness is 1.64mm

American, so I'd guess that would make it
O/D 1-7/16"
I/D 7/8"
Thick 1/16"

Whats the inner lip on the one on the right, is that hard plastic too?

That photo is of 2 identical washers.
Ones turned over so you can see both sides.
It's one piece, the lip/recess is moulded into it.
No idea if I'd need the lip if I found a generic replacement...

Volvo Peanta stern drive sealing ring ?

No, this is more washery. Flat both sides, no sealing lip or anything.
Does look kind of similar though, maybe it is a marine part of some kind.

Because its got "up" written on one face, and the direction of installation does not seem to be relevant in this application, I think it's probably a part for something else easily available that they choose to use

Find one that's close and modify.

Looks like a type of hydraulic fitting to me. Like a wiper seal or scraper, dust cap, that sort of thing.

This is what I think,
I can't find any thrust washers that are directional.
Although I think the marking on these may only be for the lip/recess.

I'd say its too hard for a sealing washer but some kind of dust cap or maybe some sort of end/bump stop..

I was hoping someone would recognise it..

I might try a Google image search with some better photos but I expect I'll just get thousands of pictures of thrust washers...

Do you not have the name of the device from which it is from?

It's from a baystar marine hydraulic steering system,
(Also branded as seastar I think)
You can sort of see the washers in the low resolution photo..
I can only find them available in a kit of spare parts at about £50 (and I need 2 pairs of them)
