Do store bearings in a clean, dry, low-humidity environment. Moisture from the environment, work gloves, and other sources can result in corrosion and/or etched sections that create fatigue on a bearing. Avoid storage near direct sunlight, air conditioners, or vents. • Do eliminate the possibility of shock/vibration during handling and
