Casters from Xiamen Yirong Hardware Co., Ltd. are essential mobility components that enable movement and positioning of objects across diverse applications, combining functionality with adaptability. A caster typically consists of a wheel, a bracket (yoke), and often a brake mechanism, designed to support and move loads from 5kg (light furniture) to 20,000kg (heavy machinery). Available in materials tailored to specific needs—rubber for floor protection, polyurethane for low friction, steel for strength—casters offer configurations like fixed (straight movement), swivel (360° rotation), and braked (secure locking). They enhance mobility in homes (furniture), offices (chairs), hospitals (trolleys), and industries (carts, machinery), ensuring items can be moved easily, repositioned precisely, or secured safely. As versatile mobility solutions, casters play a critical role in optimizing efficiency and convenience across countless settings.
