If you are Drag Racing scooters that is acceptable. However it should be a Graphite base lube.
Otherwise is is detrimental to use any sort of lube on the rollers. It WILL attract, and hold grit/dirt/whatever, and a roller can easily dislodge, and break the variator.
Now ask how I know...
The only thing that should be lubed is the drive boss, and that is ONLY on the FIRST install of a new boss/variator. Those parts are self lubing, and grease or oil interferes w/ that action.
Basically you wipe any type of oil/grease on the crank shaft, and wipe it back off. That prevents rust on the crank. Then you do the same w/ the outside of the drive boss. That tiny film is enough to begin the new parts working.
