Heavy-Duty Alloy Office Chair Replacement Casters And Wheels

This swivel caster features a composite design combining a high-strength engineering plastic wheel with a thickened iron bracket. The plastic wheel surface ensures quiet operation and prevents scratches on various flooring types-such as wood, tile, and composite materials-while the solid iron bracket provides robust structural support that resists bending or deformation under long-term loads. This combination of materials balances wear resistance with structural rigidity, resulting in an overall service life that far exceeds that of simple, all-plastic casters.
