Polyurethane-on-Iron (PU on Iron) caster wheels from Aqqcess Globe Caster are engineered for maximum strength, floor protection, and smooth ergonomic rolling in demanding industrial environments.
The polyurethane tread provides excellent floor contact and resistance to wear, while the iron core offers high structural strength and impact resistance — ideal for heavy-duty applications.

Our wheels come in diameters from 3" to 12" with tread widths between 1.5" and 2.5", available in both flat tread and round tread options to suit different floor conditions and mobility needs.
They can handle load capacities ranging from 220 lbs to 3300 lbs per caster, making them suitable for everything from medium-duty warehouse carts to high-capacity industrial transport.

Operating temperatures range from ?45 °C to 90 °C (≈ ?49 °F to 194 °F), allowing reliable performance in cold storage, ambient factory floors, or warmer environments.

Advantages of PU on Iron Wheels:
High load capacity with exceptional durability
Superior floor protection compared to cast iron or steel wheels
Smooth, quiet rolling with low push/pull effort (ergonomic)
Excellent abrasion, oil, and chemical resistance
Suitable for a wide temperature range

Applications & Industries:
Industrial carts and platform trucks
Heavy machinery handling
Warehousing and logistics centers
Manufacturing and assembly lines
Automotive and aerospace operations
Cold storage and ambient production environments

Tread Options:
Flat Tread — stable rolling, ideal for straight-line travel and load stability.
Round Tread — easier maneuverability and reduced rolling resistance, suitable for frequent turns.

Whether you need precision movement in manufacturing or rugged strength for warehouse transport, Aqqcess Globe Caster’s Polyurethane-on-Iron wheels deliver the durability and performance required for heavy-duty mobility.
