Ball Pen Tip 2

[lukin1977]

Does anyone know where can I buy like a big ball pen tip.
Ball diameter: 5 mm aprox

5 mm would be a ball bearing, wouldn't it?

I've seen paint markers that had a ball about that size in them.

Scroll down page - assorted colours. (You are probably in the US, but at least it gives a search term)

Maybe I did not explain myself good enought. I dont need a big ball pen.
I need a mechanical devise that it is similar the tip of a ball pen. But bigger

I dont even know if it exists or do I have to build it myself

Any small ball bearing from scrap yard can be sourced.

 

[ameyerrenke]

Like these? I haven't seen them smaller than this.. doesn't mean they don't exist.

These are bigger than what you are looking for, but this is what came to mind when reading your description:

[rb1957]

do you want to distribute fliud with this ?

or (like cowski posted) you just want a ball bearing in a housing ?

I think you're looking at custom. It's not clear to me that a ball-point pen tip can be arbitrarily scaled

lukin1977,
if you had one what would it do for you?

Some of those are veined tungsten carbide. Looks like worm tracks on the surface.

Multi Metals in Louisville, KY used to make balls for dot matrix printers.

We can get them for you in carbide at about any size If you nonly

Those are sometimes tungsten carbide.

They are round but not smooth. The surface looks like worm tracks to hold the ink.

We can look for them or have them made in carbide.

Personally I would try anything else first.

There is a chance that lukin1977 may return and tell us he needs the OTHER end of the pen that goes click-click... all speculation until we get a well defined problem.

 

[tbuelna]

You can use the nozzle from this device. It uses a 3/16" diameter 440C stainless steel ball, which is fairly close to 5mm diameter.

 

[VoiceOfTheBook]

What immediately springs to my mind are these. You may have to do a bit of hunting for the right size though. As others suggested, some sort of application would be useful (I know you have an application - I mean, telling us what it is).

 

[lukin1977]

Thank you very much to all. I was out of the office the past 2 days
I didn´t kwow how to call the "ball pen device". Now I know it is called BALL TRANFER.
The links that amerreyenke and cowski posted are excellent. That is just what I was looking for!

I need them for a machine that I am modifiying.
