Inline skates use either 608 standard bearings or 688 micro bearings.

I'm unsure about quads.

If you're doing large batches of bearings at a time for the rental fleet, I'd get an ultrasonic cleaner. Either for jewelry or for parts depending an what your budget will allow.

As for lube, you should use oil as an indoor rink is more sanitized compared to the street.

I'd probably rig up something like a french fryer to dip bearings in oil then let the excess drain out.

I'm experimenting with Mobil 1 0w-30. It's thinner at lower temperatures.
