About this product
Product information from the supplier.
Our Crusher Main Shaft Forgings are engineered specifically for high-demand crushing and mining operations, where components are subjected to continuous heavy impact loads and severe service environments. By implementing a precision-controlled forging route, we ensure a robust shaft preform that offers exceptional structural integrity, making it the ideal foundation for large-section machining and long-term operational stability.
Designed to minimize structural risk, these forgings are available as rough-machined blanks, meticulously prepared for the final integration of journals, tapers, and threaded ends. With a focus on optimized section transitions and heat-treatment compatibility, our main shafts provide the critical durability and dimensional allowance required by modern crusher designs to maximize equipment uptime and performance.

Frequently Asked Questions
Q: Which materials are best for crusher main shaft forgings?
Depending on the load, materials like 42CrMo4 and 35CrMo are preferred for their excellent strength-to-weight ratio and fatigue resistance, while 40Cr is often used for standard heavy-duty applications.
Q: Why choose a forged blank over a cast shaft for mining equipment?
Forging creates a continuous grain flow that follows the geometry of the part, significantly increasing impact resistance and eliminating the porosity common in castings.
Q: What is the importance of UT testing for these shafts?
Ultrasonic Testing (UT) is critical to detect any internal flaws or inclusions that could lead to catastrophic failure under the heavy cyclic loads of a crusher.
Q: Can you provide rough machining for journals and tapers?
Yes, we provide rough machining for journals, tapers, and threaded ends to reduce the final machining time for the customer while maintaining necessary stock allowances.
Q: What documentation is provided with the forging?
All shipments include full dimensional inspection reports, mechanical property verification, and EN 10204 3.1 certificates for material traceability.
Q: What is the maximum weight and size you can forge for shafts?
Our capabilities cover diameters from 300mm up to 1000mm, lengths up to 6000mm, and unit weights up to 50 tons.
