What an earth are they called......

I need to rebuild part of a mchine that has some telescopic driveshafts (about 18mm in dia)

Each end is fitted to a uk and is locked in place with a c shaped spring (10mm width) to which is fitted a cross pin. So in cross section the clip looks like a circular letter E.

I don't have the originals and I'm trying to source something similar - any idea what they are called?

Matt

Matt,

Look for either C clips or E clips, you will recognise the ones that look right

Brian

not surprisingly they are called E clips.

look on E bay.

Roy.

Do you mean lynch (or linch) pins?

I have searched for ages and C Clips or E clips are not what I am after.

Linch pin is along the principle but the spring is fixed to the end of the pin. I might need to do a sketch!!

What's "a uk"

Is this the type of clip? Used on scaffold towers

At a guess it's a Universal joint.

Tony

John - sorry, yes UJ

ASF - that's the fella but I need them to be about 18mm internal dia? Any idea what they are called?

if you right click on the above picture and choose "search google for image" there are loads of them.

Roy.

try searching scaffolding interlock clip

Roy, All I get is Boss scaffolding and these are waaaay too big for me. The type is what I am after but I am struggling (no matter what I search for) to find smaller versions. Hence my quest to find out what they are called.

Try sprong loaded retaining pin, these may do the job:

Or shaft locking pin...

Neil, I have seen these ones. I'm not sure I have the space for the bit that sticks out. In addition, these see mto start at around 28mm dia which is too large for my application.

This type of spring clip and pin is widely used in the disability aid market, for securing adjustable legs on stools etc.by the pin going through corresponding holes in an internal and external tube

They usually consist of a plastic horseshoe with a steel pin. In this context they are known as a "push-on pin clip"

Try here:-

Ah, no - didn't see any in 10mm. spring diameter. My missus has a Soari loom with adjustable-height legs that use these, but they're about 25mm/1in diameter.

Not quite what you describe but a similar device look on this link for "spring pins" **LINK**

I searched for "spring clip clevis pin" and came upon this site, hope it helps [didn't look at sizes ]

John

Thanks John - These are going to work one end but not the other as the clip had to sit on the end of the universal joint and not obstruct the sliding part.

At this rate I will end up making some from clock spring steel and riveting a pin in.

Search goes on....
