Are the stationary rollers, w/o ball bearings, good enough for short usage such as for painting wheel rims on a locomotive?
Both ball and non ball bearing sets roll and are conductive with the track so why are they sold for "non drive wheels"?
It would seem possible to apply lubricant to the non-ball rollers, if necessary, as well.
