Bearing incoming inspection checklist
A practical receiving checklist for special and non-standard bearing batches.
Identity and documents
- Part number, drawing revision, quantity and batch identity match the order
- Requested material and dimensional reports are present
- Packaging labels remain traceable to the batch
Packaging and condition
- Packaging is dry, intact and suitable for the agreed transport route
- Preservative, seals and exposed surfaces show no damage or corrosion
- Rotation is checked only by the agreed method
Dimensional inspection
- Use the drawing datums and agreed measuring equipment
- Record bore, outside diameter, width and specified runout characteristics
- Do not infer clearance or preload from free rotation alone
Nonconformity record
- Keep photos, measured values, instrument ID and sample quantity
- Quarantine affected parts and preserve packaging and batch labels
- Report the exact drawing characteristic rather than a general quality claim
