Rebuilding of shafts for Zerma ®

Shafts are one of the most critical components of Zerma industrial shredders and mills. These parts endure extreme mechanical stress and wear, leading to the key question: is it more cost-effective to invest in repairs, or should you opt for a new shaft?

The cost of a new shaft is €23,000 per unit. This option offers:

• 100% original quality and guaranteed lifespan
• Seamless compatibility with other shredder components
• The possibility of implementing the latest manufacturing technologies and materials

Repair is a more budget-friendly alternative, costing €14,500 per unit. The process includes:

• Damage diagnostics and precise wear measurement
• Repair or replacement of critical parts, such as bearing surfaces or knife grooves
• Heat treatment and balancing to optimize performance

When choosing between repair and a new shaft, key factors to consider include:
✅ Extent of damage – if wear is too severe, repair may not be efficient
✅ Operational requirements – for continuous operation, the reliability of a new shaft may be preferable
✅ Availability and delivery time – repairs might be faster than ordering a new component

While a new shaft ensures maximum reliability, repair can be a more cost-effective solution for moderate damage. The right choice depends on the component’s condition and the company's operational needs.
