Stable And Anti-Deformation Swivel 6 Inch Heavy Duty Caster Wheel For Trolley
 

Load Capacity: Strong load capacity, high safety redundancy
 

High single-wheel rated load: Conventional heavy-duty casters have a single wheel load of 150kg-1000kg, while custom models (such as those for heavy-duty shelving and industrial machinery) can reach over 2000kg.

Sufficient safety factor: The industry generally requires that the actual load should not exceed 80% of the rated load. Some high-end products are designed with a safety factor of ≥1.5 (i.e., the rated load is 1.5 times the actual maximum load) to prevent damage from sudden impact.

Features:

Wheel Structure: Most casters feature a "double-layer/multi-layer composite structure"—the outer layer is made of a wear-resistant, shock-absorbing elastic or rigid material (such as rubber or polyurethane), while the inner layer is a high-hardness wheel core (such as cast iron, steel core, or high-strength nylon). This ensures the wheel's load-bearing rigidity while reducing noise and wear during movement. Some extra-heavy-duty casters utilize a "solid wheel core" (no hollow core) to further enhance impact and crush resistance.
