A claim is decided by evidence, not by opinion. The goods, the packaging, the designation on the label and the operating conditions together show whether the bearing was non-conforming or whether it failed in service for a reason the bearing cannot control. Getting that evidence together early is what makes a claim resolvable.
| Item | Why |
|---|---|
| Photographs of the bearing | Shows the failure mode: fatigue, contamination, preload, corrosion |
| Photographs of the box label | Confirms designation and batch against the order |
| Installation details | Fit, housing, alignment, mounting method |
| Operating data | Speed, load, temperature, running hours |
| Lubricant and maintenance record | Rules lubrication in or out |
| Purchase reference | Order number and invoice |
Contamination, lubricant starvation, preload from a wrong clearance, misalignment and electrical erosion are the four most common causes of premature failure, and none of them is a manufacturing defect. They are visible in the failure pattern on the raceway — which is why photographs taken before cleaning are decisive. A bearing that failed from contamination looks completely different from one that failed from fatigue, and the difference is not a matter of opinion.
It is stated on the quotation and the invoice for the order. Report as soon as the problem appears — a delay makes the operating history harder to establish.
If it is unused, in its original packaging and a stock item, usually yes, subject to the terms on the invoice. Indent and special items are normally non-returnable.
The maker, on inspection of the returned bearing. That is why the goods must be kept and sent rather than discarded.
