Refurbish a printing roller only when the shaft, bearing seat and core are still usable and the failure is mainly in the rubber covering. Replace it when the shaft is damaged, runout is severe, the rubber layer is deeply cracked, the roller has repeated swelling, or refurbishment cost and risk approach a new roller.
Decision table
| Condition | Likely decision |
|---|---|
| Shaft and bearing seat are good; rubber is worn or aged | Refurbishment may be reasonable. |
| Severe runout, bent shaft or damaged bearing seat | Inspection first; replacement may be safer. |
| Repeated swelling or chemical attack | Check consumables and material compatibility before refurbishing. |
| Unclear failure cause | Use inspection report and photos before quoting. |
Evidence to prepare
- Full roller photo, shaft-end photo and close-up of damaged rubber.
- Machine model, roller position and service time.
- Current print defect and failure frequency.
- Known hardness, diameter and runout if measured.
- Ink, cleaner, coating and storage conditions.
