Small metal caster wheels from Xiamen Yirong Hardware Co., Ltd. pack durability into a compact design, ideal for small equipment, tools, or machinery requiring robust mobility in tight spaces. With a diameter of 2-5 inches, these wheels—crafted from steel or cast iron—support 100-1,000kg, punching above their size class to handle small industrial tools, medical devices, or heavy-duty storage carts. Metal construction ensures resistance to wear, impact, and high temperatures (up to 200°C), making them suitable for workshops, laboratories, or factory corners. Treads may be plain steel (for maximum strength) or coated in rubber/polyurethane for grip and floor protection. Swivel models feature precision ball bearings, enabling 360° rotation for maneuvering in confined spaces like under workbenches or between equipment. These small metal caster wheels balance compactness with strength, ensuring even heavy small items can be moved easily and safely.
