Ball bearing or sleeve? Ceramic balls can be run without lube but in this application it makes little to no difference,
probably measured in microwatts. If shipped without lube, that is the way I would run it. FWIW ceramic bearings
were originally designed for applications running at thousands to 10s of thousands of RPM and temperatures
upwards of 800 degrees C. In bicycle applications they are designed to extract the maximum $$ from the end user.
