Heavy-duty casters generally refer to caster assemblies with a single wheel rated load capacity ≥150kg (some industry standards define ≥200kg as heavy-duty, depending on the application scenario). They can withstand high-frequency, high-load use for a long time, and are impact-resistant, wear-resistant, and adaptable to complex ground environments (such as bumps, oil stains, and high temperatures).



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.
