4x2 Rubber Wheel for Casters: Durability & Performance Guide

Aluminum hubs are designed for lighter loads and provide corrosion resistance, while cast iron hubs are built for heavy-duty industrial applications that require maximum strength and durability. The choice depends on your specific weight capacity and environmental requirements.

Standard 70 Shore A durometer provides excellent shock absorption and floor protection, while harder options up to 90 Shore A offer decreased roll resistance for easier movement of heavy loads. Higher durometer wheels roll more easily but may provide less cushioning.

No, rubber wheels are non-marking and specifically designed to protect both loads and floors during transport operations. They provide excellent floor protection compared to harder wheel materials like metal or hard plastic.

These wheels are widely used in manufacturing for industrial carts and production line equipment, warehousing for dollies and material transport, office environments for computer equipment mobility, and healthcare for medical carts requiring quiet operation.

Yes, 4x2 rubber wheels are available in standard and crowned tread patterns to suit different application requirements. The tread pattern choice affects traction, maneuverability, and performance characteristics for your specific use case.

Weight capacity varies by hub material and rubber hardness combination. Contact the technical team at 1-800-733-4758 for specific load ratings based on your hub material choice and durometer requirements to ensure proper wheel selection for your application.
