Polyurethane cart wheels from Xiamen Yirong Hardware Co., Ltd. are versatile, high-performance components engineered to meet the demands of diverse cart applications, from light-duty utility transport to medium-heavy industrial handling. Made from industrial-grade polyurethane, these wheels are available in a range of formulations to suit specific needs: cast PU for superior impact resistance, extruded PU for consistent thickness, and reinforced PU (blended with fiberglass or carbon fiber) for enhanced load capacity. Their key advantage lies in their unique combination of properties: they offer the elasticity of rubber to absorb vibrations—protecting fragile items like electronics or glassware during transport—paired with the hardness of plastic to resist deformation under heavy loads, supporting up to 200 kg per wheel in medium-duty configurations. The low rolling resistance of PU (approximately 0.02-0.04 coefficient of friction on concrete) ensures carts glide smoothly, reducing operator fatigue in settings where carts are pushed frequently, such as warehouses, workshops, or retail stockrooms. These wheels are highly resistant to common retail and industrial contaminants, including cleaning agents, motor oils, and food-grade lubricants, making them suitable for carts used in restaurants, auto shops, and food processing facilities. Their non-marking treads protect sensitive floors like polished concrete in showrooms or hardwood in offices, while their durability ensures they withstand the rigors of daily use on rough surfaces like factory floors or outdoor pavements. Whether mounted on logistics carts moving packages, tool carts transporting equipment, or service carts in hospitality settings, polyurethane cart wheels deliver reliable, long-lasting performance tailored to dynamic operational environments.
