Product Description
Inside the brutal environment of a cone crusher, the head nut (or main shaft nut) is the single component responsible for securing the mantle against immense crushing forces and constant, violent vibration. A standard nut will not survive. A failing nut leads to catastrophic damage and costly downtime.
Yile Machinery manufactures heavy-duty, forged steel head nuts engineered to provide unwavering clamping force and exceptional resistance to loosening, ensuring your crusher operates safely and productively.
Every aspect of our head nuts is designed to outperform and outlast cast or lower-quality alternatives in high-stress crushing applications.
We start with high-grade alloy steel, typically 42CrMo, known for its exceptional toughness and tensile strength. The steel is then forged, not cast, which creates a dense, uniform grain structure that is highly resistant to shock loads and fatigue cracking—the primary failure modes for crusher components.
The threads are the heart of the nut. Our threads are machined on CNC lathes to exact OEM specifications.
Smooth Installation & Removal: Precision threads prevent galling and stripping during mantle change-outs, saving valuable maintenance time.
Even Load Distribution: A perfect thread profile ensures that the clamping force is distributed evenly, maximizing holding power and preventing thread failure under load.
Whether you are performing standard maintenance or have a custom requirement, we have the solution.
Direct OEM Replacement: We can supply head nuts for a vast range of crusher models.
Reverse Engineering: Provide us with a sample—even a worn or damaged one—and we can reverse-engineer it to create a brand new, dimensionally perfect replacement.
We manufacture high-quality, direct-fit replacement main shaft nuts for cone and gyratory crushers from leading manufacturers, including:
Metso™: For HP™ series (HP200, HP300, HP400, HP500), GP™ series, and Nordberg™ models.
Sandvik™: For CH™ series (CH430, CH440, CH660) and CS™ series hydrocone crushers.
Telsmith™
Terex™ / Powerscreen™
And many other brands.
Disclaimer: Yile Machinery is not an authorized dealer for the listed brands. All brand names and part numbers are used for identification purposes only.
Certified Material: We provide full material certification (chemical and mechanical properties) for every batch.
100% Dimensional Inspection: Every nut is checked for critical dimensions, including thread profile, pitch, and overall geometry.
Thread Gauge Verification: We use certified thread gauges to ensure a perfect fit with the main shaft.
