V-Rail Options

[keyne]

Dear Zoners,

i compiled a PDF Document with 10 options for rails for V-rollers. It contains a sketch and a couple of descriptions/strong and weak points for each option.
Please take a look and tell me which option you would use or what you have tried and how it worked for you. I will add new comments and new ideas to the PDF.

#11 - 2 of the #1's, one top and one bottom, which is the way they are meant to be used. If only used on top, the wheel can rotate a little bit with axial forces. By using the V rollers top and bottom, it eliminates the possibility of side to side play, or flexing.

added #11 and #12.

hope this is useful for some..

#11, you can mount the center piece to machine, then use an e-longated (spelling) hole on the top and bottom pieces to bolt to the center piece every 6-8 inches to allow for percise alignment.

I use the Unistrut #5 for a moving table. I have 2 rails. The length is ~45" and the table rolls on the outer lips of the unistrut. I use 2 skate bearings separated by a nut. Gives just enough width to grab the rail and stay put. There are 3 sets of bearings on both sides. Table weight holds it in place.

I have seen no issues with flex or overall strength.
