Small plastic caster wheels from Xiamen Yirong Hardware Co., Ltd. are lightweight, cost-effective mobility solutions for lightweight items and tight spaces, combining simplicity with functionality. With a diameter of 1-4 inches, these wheels—crafted from high-impact polypropylene or nylon—support 5-100kg, making them ideal for toy carts, small furniture (stools, end tables), office supplies trolleys, or hobby equipment (3D printers, model workbenches). Treads are smooth to glide over carpet, hardwood, or tile, with minimal noise to avoid disrupting quiet environments like offices or bedrooms. Swivel models feature a tight turning radius, enabling easy maneuvering in closets, under desks, or on crowded workbenches. Mounting options include threaded stems, adhesive backs, or small plate mounts, ensuring easy installation without specialized tools. These casters offer practical mobility for light-duty applications, balancing affordability with reliability.
