Durable caster wheels from Xiamen Yirong Hardware Co., Ltd. are engineered for extended service life in harsh conditions, resisting wear, corrosion, and impact to minimize replacement frequency. Crafted from premium materials, these wheels are available in options like high-density polyurethane (with a cross-link density of 80+%), which resists tearing and abrasion; glass-reinforced nylon (30% glass content), offering exceptional strength and chemical resistance; and hardened steel (55-60 HRC), capable of withstanding contact with sharp debris. Each material is chosen for its ability to maintain structural integrity over 50,000+ rolling cycles on rough surfaces like concrete, asphalt, or metal floors. These casters support loads from 50-3,000kg, with designs optimized for specific applications: polyurethane wheels excel in indoor settings (factories, warehouses) for their floor protection, while steel wheels thrive in outdoor or heavy industrial environments (construction sites, mining). Sealed bearings—filled with high-temperature lubricant—prevent contamination, ensuring smooth rotation even in dusty, wet, or chemically exposed environments. Whether mounted on light office furniture or heavy machinery carts, these durable caster wheels deliver consistent performance, reducing operational costs by extending service intervals.
