High-Performance Bronze Head Nuts & Main Shaft Nuts for Crushers

Yile Machinery is a leading manufacturer of OEM and aftermarket bronze wear components, specializing in head nuts, main shaft nuts, and locking nuts for cone and gyratory crushers. Engineered for precision and extreme durability, our bronze nuts ensure secure clamping force and reliable performance in the harshest mining and aggregate environments.

The Critical Role of a High-Quality Bronze Nut

The main shaft nut is a critical component that secures the mantle or concave liners. A failure in this part can lead to catastrophic damage and extended downtime. We manufacture bronze nuts that outperform standard parts by focusing on two key areas:

1. Superior Material Properties: We use high-grade bronze alloys, primarily Aluminum Bronze (e.g., C95400, C95800) and Tin Bronze (e.g., C93200) . These materials are chosen for:

• Excellent Wear Resistance: Withstands the intense vibration and friction of crushing operations.

• High Compressive Strength: Maintains clamping force without deforming.

• Prevents Galling: The bronze material prevents the nut from seizing (cold welding) onto the steel main shaft, which makes disassembly for liner changes significantly easier and safer.

2. Advanced Manufacturing Process:

Unlike simple sand castings, our premium bronze nuts are produced using centrifugal casting. This process creates a much denser, finer grain structure that is free from porosity and inclusions. The result is a mechanically superior component with significantly higher strength and fatigue life.

Our Manufacturing & Machining Capabilities

• Centrifugal Casting: Produces metallurgically superior bronze blanks.

• Precision CNC Threading: We can machine any thread profile—including large ACME, trapezoidal, and custom multi-start threads—to exact OEM specifications.

• Tight Tolerance Machining: All dimensions are precision-machined to guarantee a perfect fit.

• Material Certification & Analysis: Full traceability and chemical/mechanical property reports available on request.

• Reverse Engineering: We can create a new, production-ready drawing from your worn or damaged sample part.

Applications for Custom Bronze Nuts

While our primary focus is on the mining sector, we manufacture large, heavy-duty bronze nuts for various industries:

• Cone & Gyratory Crushers: Head Nuts, Main Shaft Nuts, Locking Nuts, Bowl Nuts.

• Forging & Stamping Presses: Adjustment Screw Nuts, Lead Screw Nuts.

• Marine Propulsion Systems: Propeller Shaft Nuts.

• Heavy Industrial Gearboxes & Rotating Equipment.
