Store bearings flat, in a vibration-free, dry area with a cool, steady temperature.
Control and limit the relative humidity of the storage area as follows:
• 75% at 20 °C (68 °F)
• 60% at 22 °C (72 °F)
• 50% at 25 °C (77 °F)
Keep bearings in their original unopened packages until immediately prior to mounting to prevent the ingress of contaminants and corrosion.
Bearings that are not stored in their original packaging should be well protected against corrosion and contaminants.
