Repair of Old Cores / Spindles

The cores of Rubber Rollers on continuous process, gets worn out, resulting in imbalance and other difficulties in smooth operations, so we also offer our services for repairing your old used worn out rollers.

For this process following measures are taken into consideration :

• Complete journal repairing.
• Replacement of broken journal.
• Repairing bearing seats by welding oversize and then turning to desired dimensions.

Also, the cores are checked by our engineers to ensure :

• Dimensional accuracy as per drawing
• Static or Dynamic accuracy as per requirement.
• Non destructive testing for defect free material, if required.

Re-Coating of Rubber on Repaired Old Cores/Spindles

After repairing your old core / spindle, the old worn rubber is stripped and its re-coating with new rubber. This further involves curing process, precision grinding, polishing and final inspection.

Your used roller becomes a "like new" roller at a reduced cost and delivery time.
