Polyurethane shopping cart wheels from Xiamen Yirong Hardware Co., Ltd. are a premium mobility solution designed to address the unique challenges of retail environments, where durability, user comfort, and floor preservation are paramount. Constructed from high-performance polyurethane with a carefully calibrated hardness of 70-85 Shore A, these wheels strike the perfect balance between flexibility and strength: they glide effortlessly over common store surfaces—tile, linoleum, and low-pile carpet—while maintaining enough rigidity to support loads of up to 120 kg per wheel, easily handling a cart filled with groceries, household goods, or bulk items. Their tread design features a series of micro-grooves that channel away water, dust, and small debris, preventing buildup that could cause uneven rolling or squeaking. Unlike rubber wheels, which may harden or crack over time due to exposure to sunlight or cleaning chemicals, these PU wheels exhibit exceptional resistance to aging, retaining their elasticity and performance for years even in busy supermarkets with high daily cart usage. The material’s smooth, non-marking surface ensures they leave no scuffs or black streaks on polished floors, a key benefit for high-end retail spaces or malls where maintaining a pristine appearance is critical. Designed to fit standard shopping cart axles (typically 12-16 mm in diameter), they feature precision bearings that reduce friction, making it easy for customers of all ages and strengths to maneuver loaded carts through crowded aisles or narrow checkout lanes. By combining low maintenance needs, quiet operation, and consistent performance, these polyurethane wheels enhance the shopping experience while reducing long-term replacement costs for retailers.
