These rollers run on one side of the track only.
This would require you to use two tracks mounted top to bottom to provide a linear bearing.
That would be 4 tracks per axis.
There might be some track that would allow you to mount a bearing on each side
or you could run two tracks, one on each side of your axis, with the rollers opposed to each other similar to how v bearings are used.
The mounting of the tracks will also require some thought, because this is a channel and rubbish will build up easily and cause problems.
