Overview
This heavy-duty industrial caster is engineered to provide superior mobility and equipment protection in demanding environments. Featuring a robust iron core construction paired with a high-grade polyurethane wheel, this unit delivers exceptional load-bearing capacity while minimizing floor damage. The integrated dual-spring shock absorption system effectively isolates sensitive machinery from vibrations and impacts caused by uneven flooring or rough transit conditions. Designed for static loads up to 771 lbs per unit, this caster ensures stability and smooth maneuverability for heavy transport carts, manufacturing equipment, and material handling systems.
Key Features
Dual-spring shock absorption mechanism reduces vibration transmission to loaded equipment Non-marking polyurethane tread protects delicate factory floors and prevents scuffing Robust iron core provides structural integrity under extreme weight conditions High static load capacity of 771 lbs per individual caster unit Smooth rolling performance on both level and irregular surface textures Corrosion-resistant finish suitable for humid or washdown environments Precision-engineered bearing race for reduced rolling resistance

Applications
Heavy machinery transportation and positioning Industrial assembly line carts and trolleys Medical equipment movement in hospital settings Audio-visual rack mobility for stage and studio use Food processing equipment requiring frequent sanitation Warehouse logistics and pallet jack modifications Laboratory instrument transport where vibration control is critical Uneven surface navigation in construction or outdoor storage areas The combination of a wide 2.0-inch wheel profile and the resilient polyurethane compound allows for easy initiation of movement even when fully loaded. The mounting plate configuration utilizes a standard bolt pattern that simplifies retrofitting onto existing equipment or integration into new custom builds. With an overall height of 8.7 inches, these casters provide adequate ground clearance while maintaining a low center of gravity for enhanced safety during transport. The shock-absorbing capability is particularly beneficial for transporting fragile instruments or precision tools that could be damaged by constant jarring. Each package contains four complete units, providing a full set for standard four-wheel cart configurations or replacement needs for large-scale fleet maintenance.
