Which statement correctly describes the storage of a new rolling element bearing?

• A. Store in a humid environment to prevent drying
• B. Store clean, dry low-humidity environment; flat in a vibration-free area
• C. Store on a shelf with other metal parts
• D. Submerge in mineral oil

Answer: (B)

Keep bearings in a clean, dry environment with low humidity and lay them flat in a vibration-free area. This protects the bearing surfaces from rust and contamination and prevents deformation or brinelling of the races while it’s waiting to be installed. A humid environment invites corrosion, submerging in oil can attract dirt and create handling problems, and storing with other metal parts can cause scratches or contamination. The specified storage conditions minimize corrosion, keep surfaces pristine, and maintain dimensional integrity until use.
