Industrial Ductile Iron Wheel

Product Features & Details

Exceptional Impact Resistance: Unlike standard gray cast iron, the nodular (spherical) graphite structure of ductile iron allows the wheel to absorb heavy shocks and impacts without brittle fracturing or shattering.

Massive Load Capacity: Capable of supporting multi-ton loads safely, making it ideal for the heaviest industrial carts, scrap bins, and material handling equipment.

Cost-Effective Strength: Delivers performance and safety levels very close to forged steel, but at a significantly lower production cost, providing excellent ROI for heavy-duty fleets.

Precision Machined Tread: The wheel face is CNC-machined for smooth rolling and perfect concentricity, drastically reducing rolling resistance and operator fatigue.

High Wear & Abrasion Resistance: The hard metal surface easily powers through metal shavings, debris, and rough concrete floors that would quickly destroy polyurethane or rubber wheels.

Temperature Resilient: Capable of operating in high-heat environments (ovens, foundries) when equipped with appropriate high-temperature bearings and lubrication.

Key Attributes & Specifications

Material: Premium Ductile Iron (Nodular Cast Iron, e.g., ASTM A536).
Hardness: Typically 160 - 220 Brinell (HB).
Tensile Strength: 60,000 to 80,000 PSI (Significantly higher than standard cast iron).
Bearing Options: Available with heavy-duty tapered roller bearings, precision ball bearings, or plain machined bores.

Frequently Asked Questions (FAQ)

Q: What exactly makes Ductile Iron different from standard Cast Iron?
A: Standard cast iron (gray iron) contains flakes of graphite, which create stress points that can lead to cracking under heavy impact. Ductile iron is treated with magnesium to change the graphite into spheres (nodules). This removes the stress points, making the iron much more flexible, durable, and resistant to shattering.

Q: Can ductile iron wheels handle high-speed towing?
A: Yes, when equipped with high-quality tapered roller bearings, ductile iron wheels are excellent for power-towed applications in automotive plants and heavy manufacturing, as they can handle both the speed and the impacts of rough floors.

Q: Will these wheels damage a concrete floor?
A: Like all hard metal wheels, ductile iron can cause wear, scratching, or deterioration on standard concrete floors, especially under extremely heavy loads or when turning. They are best suited for steel-plated floors, tracks, or rough industrial concrete where floor preservation is not the primary concern.

Q: Do you offer these with V-grooves or Flanges?
A: Absolutely. Because ductile iron is highly machinable, we can easily custom-machine V-grooves or single/double flanges into the tread for track-guided applications.
