Multi purpose small caster wheels from Xiamen Yirong Hardware Co., Ltd. are compact, adaptable components designed to meet diverse mobility needs across applications, where space and versatility are key. These casters have a diameter of 1.5-4 inches, making them suitable for small furniture (stools, end tables), utility carts (tool carts, office supply trolleys), medical devices (portable monitors, small pumps), and hobby equipment (3D printers, model workbenches). Available in materials like rubber, polyurethane, and plastic, they cater to different surface and load requirements: rubber for shock absorption and floor protection, polyurethane for low rolling resistance and durability, plastic for cost-effectiveness in light-duty tasks. Many models feature swivel functionality with a 360-degree rotation range, allowing easy maneuvering in tight spaces like closets, under desks, or between laboratory equipment. They support loads from 10 kg (for tiny plastic casters) to 150 kg (for sturdier rubber or polyurethane variants), ensuring they can handle everything from lightweight toys to small industrial tools. Mounting options are diverse, including threaded stems, adhesive backs, and small plate mounts, ensuring compatibility with various equipment bases. These casters are designed for easy installation and maintenance, with many featuring press-fit or snap-on designs that require no specialized tools. Whether used in homes, offices, laboratories, or workshops, multi purpose small caster wheels deliver flexible mobility, adapting to changing needs with ease.
