How to stock and maintenance my bearings right?

Do not store bearings directly on concrete floors, where water can condense and collect on the bearing; - Store the bearings on a pallet or shelf, in an area where the bearings will not be subjected to high humidity or sudden and severe temperature changes that may result in condense forming; - Always put oiled paper or, if not available, plastic sheets between rollers and cup races of tapered roller bearings.
