bellows shaft guards

bellows shaft guards

(OP)
Does anyone know any suppliers in the UK of leadscrew type guards. Preferably steel, concertina or spiral. Can't seem to find anything on the net. I need to cover a thread & it extends from 35mm to about 220mm I am also very restricted on outside & inside dias.
Thanks

RE: bellows shaft guards

Those are pretty cool.  Has anybody used them on an air cylinder instead of a lead screw?

RE: bellows shaft guards

Here is another source that says it has world wide coverage.

I never seen this type cover used on pneumatic/hydraulic cylinders. The ones we used were somewhat limited in speed, extension and retraction, department.

I have seen the pleated type used on smaller cylinders.

RE: bellows shaft guards

Thanks Unclesyd.  Their website shows the cylinder rod as a potential application, so I'm going to dig a little deeper.

We have used these on leadscrews where the movement was fairly slow and there was a lot of background motor/gearbox noise.

We did try one out on an air cylinder for a piece of laboratory equipment and although it worked fine, we had concerns about the metal on metal "sliding" noise that was apparent with the relatively fast moving and otherwise silent air cylinder. This was helped by the using some PTFE dry-lube and it would have probably been OK, but as the machine was otherwise completely silent and because we were sending it to the other side of the world, we didn't want to take a chance with it scuffing and getting really noisy, so as it was only short stroke, we used rubber bellows instead.

However, this was a long while ago and I expect the technology has moved on since then, especially in surface treatment to minimise noise and scuffing but I thought I should mention this.
