Unable to resist a chance to look like an idiot...a number of PN's bearing sets - such as PN Racing Mini-Z AWD Shield Hub Dry Ball Bearing Set (part no 600128) are listed as being 'dry'. Does this just mean they are shipped dry and need lubing before use - or are they actually expected to run lube free for life?

Believe they come without grease and you can choose whether to add your lube or run dry. Dry bearings spin faster but have a shorter lifespan.

It means that they do not use a thick grease/lubricant from the factory like many bearings do. Many racers clean the grease/lubricants out of normal bearings to have them spin more freely. Not sure whether these dry bearings use a powder lubricant or not, so if you clean them, you may want to use a thin bearing oil to keep them lubricated.
