I need to build something with slides that will travel with a small amount of friction, will these be suitable? Thanks. http://uk.rs-online.com/web/p/linear-guides-rails/4885057/ Edited By Chris Denton on 23/11/2016 21:51:27 |

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

5563 forum posts 322 photos | 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.
