Cast Iron Wheel for Heavy Loads

Product Features & Details

Extreme Load-Bearing Capacity: Manufactured from high-tensile gray iron (Class 30 or higher), capable of supporting the heaviest industrial loads without risk of breakage or deformation.

Superior Heat Resistance: Naturally capable of operating in extreme temperatures (up to 400°C+ depending on bearing type), making it ideal for ovens, furnaces, and autoclaves.

Low Rolling Resistance: The precision-machined, hard metal tread ensures the lowest possible friction on smooth concrete or steel tracks, reducing energy consumption for drive systems.

Exceptional Wear & Abrasion Resistance: Highly resistant to sharp debris, metal shavings, and abrasive floor conditions that would shred rubber or polyurethane wheels.

Long Service Life: Designed for decades of use, these wheels are nearly indestructible under normal operating conditions and require minimal maintenance beyond periodic lubrication.

Stable Static Loading: Unlike plastic wheels, cast iron will never develop "flat spots," regardless of how long a heavy load remains stationary.

Key Attributes

Material: High-Quality Gray Cast Iron (ASTM A48 Class 30/35).
Hardness: Typically 180 - 220 Brinell (HB) (Custom induction hardening available for the tread).
Temperature Range: Reliable from -40°C to +425°C (Requires high-temp grease/bearings for extremes).
Core Configuration: Available with precision ball bearings, tapered roller bearings, or heavy-duty plain bore bushings.

Frequently Asked Questions (FAQ)

Q: For which applications are Cast Iron Wheels best suited?

A: Cast iron wheels offer numerous advantages that make them suitable for a wide variety of applications. If you are seeking wheels for high-temperature environments, cast iron wheels are undoubtedly an ideal choice, boasting a temperature rating of up to 800 degrees Fahrenheit. Furthermore, cast iron wheels are an excellent option for heavy-duty applications, as they offer a load-bearing capacity of up to 10,000 pounds.

Q: What is the main difference between Forged Steel and Cast Iron Wheels?

A: Although they may sound similar, there are significant differences between cast iron wheels and forged steel wheels. Forged steel is produced through a hot forging process—a method far more complex than the smelting process used to manufacture cast iron. Consequently, forged steel costs approximately 30% to 50% more than cast iron, yet it boasts twice the strength. Cast iron has a load-bearing capacity of approximately 10,000 pounds, whereas forged steel offers a capacity of up to 20,000 pounds.

Why Choose AstraRoll?

Precision Engineering Support

CNC Machining Excellence: Every wheel is precision-turned to ensure perfect concentricity (TIR), preventing the vibration and "clatter" often associated with lower-quality cast wheels.
Drawing Conversion: We help you upgrade your existing equipment by providing custom-sized cast iron wheels designed to match your specific OEM axle and housing dimensions.

Quality-Centric Manufacturing

Internal Integrity: Our casting process is strictly controlled to eliminate internal air pockets or "blow holes," ensuring the wheel remains structurally sound under maximum impact.
Versatile Finishing: From rust-resistant paints to high-gloss industrial finishes, we customize the appearance and protection level to suit your facility's environment.
