High load capacity cart wheels from Xiamen Yirong Hardware Co., Ltd. are built to be workhorses in heavy-duty material handling, combining robust construction with advanced engineering to support extreme weights while maintaining maneuverability. These wheels start with a foundation of heavy-gauge steel brackets, often powder-coated for corrosion resistance, which provide a stable mounting point and distribute stress evenly across the cart frame. The wheel itself features a multi-layer design: a rigid inner core (steel or high-density polymer) that resists deformation under pressure, surrounded by a thick tread of polyurethane or rubber compounded for high load-bearing capacity—these treads can compress by less than 5% even under 1,500 kg of weight, ensuring consistent rolling performance. Their bearing systems are oversized and precision-machined, using high-carbon steel balls or roller bearings that reduce friction and handle radial and axial loads without overheating. These wheels are designed to operate on rough surfaces, with tread patterns that channel away debris like gravel or metal chips, preventing punctures or uneven wear. In testing, they demonstrate exceptional durability, maintaining functionality after 10,000+ cycles of rolling under maximum load on concrete floors—equivalent to years of use in a busy warehouse. Suitable for carts used in industries such as automotive manufacturing, construction, and heavy logistics, these high load capacity wheels ensure that even the heaviest loads can be moved safely and efficiently, reducing downtime and improving operational productivity.
