Wear resistant heavy duty casters from Xiamen Yirong Hardware Co., Ltd. are built to endure the most abrasive and demanding industrial environments, combining extreme wear resistance with high load capacity to ensure long-term performance. These casters are constructed using premium materials selected for their ability to withstand continuous friction and impact: their wheels are made from high-density polyurethane with a Shore hardness of 90-95, which resists abrasion 30-50% better than standard polyurethane; glass-filled nylon, which maintains its structural integrity even after contact with rough concrete or metal surfaces; or forged steel with a hardened chrome plating, capable of withstanding scratches and wear from sharp debris like nails or gravel. The caster brackets are crafted from thick, high-strength steel (3-5 mm gauge), with reinforced welds and gussets that distribute weight evenly and prevent bending under loads of 1,000-5,000 kg per caster. To enhance wear resistance further, the wheel bearings are oversized and made from high-carbon steel, with seals that prevent the entry of dust, dirt, and industrial fluids—ensuring smooth rotation even in dirty environments. These casters are designed for use in heavy-duty applications: factory carts transporting metal components, construction trolleys moving building materials, and warehouse transporters carrying full pallets. In field tests, they demonstrate exceptional longevity, maintaining functionality after 200,000+ cycles of use in harsh conditions, making them a cost-effective choice for industries where downtime and replacement costs are critical concerns.
