Long-term storage at moderate temperatures in low humidity environments have little effect on many low-additive, well-formulated lubricants. More about lubricant storage life limits.

From "Practical Plant Failure Analysis"

There have been many studies that have shown that water contamination reduces the fatigue life of rolling element bearings. From 1960 to date, we are aware of at least seven extensive analyses, none of which had the operating conditions duplicating other studies. Based on them, we feel that there can be a consistent reduction in life at water concentrations as low as 0.01% (100 ppm) and recommend that water levels be kept below half of that (50 ppm).
