Journal Repair – Embossing Roll

The embossing roll required journal repair due to worn-out bearing fits.  The roll was inspected and a crack was revealed on the tending end. Our team proposed a re-journal and manufacturing a carrier ring that would turn concentric to the OD of the roll. The drive end showed no cracks and thermal spray repair was found suitable to return the bearing fit to OEM specifications. See our complete engineered solutions that provided an effective cost-effective solution that meets the customer’s timeline.
