Heavy-duty small caster wheels from Xiamen Yirong Hardware Co., Ltd. deliver impressive load capacity in a compact design, ideal for small equipment, tools, or machinery requiring mobility in tight spaces. With a diameter of 2-5 inches, these casters—crafted from steel-core polyurethane, reinforced nylon, or hardened steel—support 100-1,000kg, making them suitable for small industrial tools (drill presses, grinders), medical devices (portable imaging machines), or heavy-duty storage carts. Their compact size allows maneuvering in confined spaces like workshop corners, laboratory benches, or factory aisles, while swivel functionality (enabled by precision bearings) ensures easy direction changes. Treads are designed to resist wear and protect floors, with options like rubber coatings for grip or polyurethane for low friction. Optional brakes secure positioning during use, enhancing safety. These casters prove that small size doesn’t compromise strength, making them essential for compact heavy-duty applications.
