EZE® Shaft Repair Sleeves

EZE® Shaft Repair Sleeves: Durable and Efficient Shaft Restoration

The EZE® shaft repair sleeves offer a highly effective and environmentally friendly solution for restoring damaged shaft surfaces. Manufactured from high-quality C 22 steel (SAE 1020) and featuring a fine-bored inner surface, they guarantee crack- and failure-proof performance under normal bearing stress. This keeps your shafts free from welding-induced stresses and porosity, ensuring a long-lasting repair.

Your Benefits and Technical Details

• High Material Quality: Made from robust C 22 steel (SAE 1020) for maximum resilience and longevity.
• Optimized Surface Finish: The fine-bored inner surface ensures a precise fit and reduces friction.
• Crack- and Failure-Proof: Guarantees maximum reliability and safety under normal operating conditions.
• Weld-Free Repair: Avoids welding-induced stresses and porosity, preserving the shaft's integrity.
• Environmentally Friendly Solution: A sustainable alternative to manufacturing new shafts, conserving resources.

Installation Instructions: For a Perfect Shaft Repair

1. Preparation: Clamp the rotor in a lathe and align it precisely. If necessary, use a steady rest, bore out the shaft center hole, and then insert a circumferential live center.
2. Measure Dimensions: Carefully record the exact dimensions of the bearing surface (diameter, length) and the seal surface (if machining is required).
3. Machine the Shaft: Turn down the shaft to a diameter that is exactly $0.05 \text{ mm}$ larger than the inner diameter of the EZE® repair sleeve.
4. Mount the Sleeve: Heat the EZE® repair sleeve and precisely shrink-fit it onto the prepared shaft.
5. Adjust Seal Surface: Machine the sleeve section over the seal surface to the exact bearing size.
6. Machine Bearing Surface: Subsequently, bring the main bearing surface to the required dimension.
7. Finish Seal Surface: Machine the seal surface to the original starting dimension.
8. Process Edges: Carefully chamfer sharp edges to prevent damage.
9. Final Finishing: Use fine emery cloth to bring the sleeve to the exact final dimension and achieve a good polish for optimal function.
10. Ready for Installation: After these steps, the repaired shaft is ready for installation.
