Low friction small caster wheels from Xiamen Yirong Hardware Co., Ltd. are engineered to minimize resistance, ensuring effortless movement of small items and equipment in tight spaces. These casters have a diameter of 1.5-4 inches, with a compact design that makes them suitable for small furniture, utility carts, medical devices, and precision equipment where even minor friction can hinder mobility. Their low friction performance is achieved through a combination of materials and design: wheels are made from high-quality polyurethane or polished nylon with a smooth, hard surface (Shore hardness of 70-90 A) that reduces contact friction with floors. The wheel hubs contain precision ball bearings, often sealed and pre-lubricated, that minimize internal friction, allowing the wheels to spin freely with minimal force. Swivel variants feature a raceway with hardened steel balls that enable 360-degree rotation with almost no resistance, ensuring tight turns and easy maneuvering in confined spaces like under desks, on laboratory benches, or in retail display areas. Tread patterns are minimal, with a flat or slightly rounded surface that reduces contact with surface irregularities, further lowering friction. These casters support loads of 10-150 kg, making them ideal for applications from lightweight office tools to small industrial instruments. Whether rolling over carpet, tile, or hardwood, low friction small caster wheels ensure movement requires minimal effort, enhancing efficiency and reducing operator fatigue.
