- Bearing System: Equipped with a double ball bearing mechanism, this product supports a total capacity of 300kg (75kg per caster). The steel plate construction ensures durability and prevents deformation under heavy loads, making it essential for moving equipment in warehouses and industrial facilities. - Accurate Rotation Mechanism: Features a 360-degree rotation design with a sealed bearing system that reduces roller resistance by 45% compared to single bearing models. This allows for smooth and precise direction changes, enhancing operational efficiency. - Nylon Construction: Crafted with a 2-inch diameter nylon body rated at 95A hardness, this caster resists abrasion on concrete and rough surfaces. It maintains its structural integrity in temperature ranges from -20 °C to 80 °C, ensuring reliable performance for outdoor applications. - Universal Installation Ready: The standard 7.4 x 5 cm mounting plate is compatible with most carts. Pre-drilled holes accommodate M6 bolts (not included), simplifying retrofitting for existing devices in hotels, retail stockrooms, and other settings. Use Scenarios: 1. Warehouse Operations: Ideal for transporting heavy inventory across loading docks and storage areas, enhancing productivity. 2. Retail Stockrooms: Perfect for retrofitting existing carts, allowing for easy movement of stock without compromising stability. 3.
