Practical answer
Keep bearings away from moisture, dust, corrosive chemicals and walls or floors where condensation can form. Repeated temperature change may create moisture inside the package and gradually damage corrosion protection.
Do not unpack bearings unnecessarily or touch working surfaces with bare hands. Follow manufacturer guidance for support, orientation and long-term inspection of large bearings. Isolate and assess any item with damaged packaging or corrosion marks.
On-site checks
- Integrity of original packaging and corrosion protection
- Humidity, cleanliness and temperature variation
- Distance from chemicals, water sources and the floor
- Support and orientation of large bearings
Record for enquiry or analysis
- Receipt date, batch and complete designation
- Packaging damage or opening history
- Dates of visual and corrosion-protection checks
- Inspection decision after the recommended storage period
