Linear Slide Fricion.

[Chris DentonParticipant @chrisdenton53037]

 

I need to build something with slides that will travel with a small amount of friction, will these be suitable?

Thanks.

I'd like to be able to offer an opinion but really you are the only person that knows what 'small amount' is acceptable.

That's true!

It should be able to move by pushing with your little finger using moderate force!

What's it made of, what weight is on it, how fast does it move, and how often. There are probably a few more questions that should be asked.

I suggest that you look at linear ball bearings as used in 3D printers, significantly cheaper and use ground silver steel bars. See here for example. Friction is very low, if you need more you could always add a "brake" of some kind.

Better to use those bearings with shafting like this rather than silver steel which will need hardening and is likely to distort.

As said above though it does really depend on your application.

When I was working I regularly bought from bearing suppliers "Linear Shafting" and linear bearings. For what you get not pricey either.
