Heavy-duty casters for warehouses from Xiamen Yirong Hardware Co., Ltd. are optimized to meet the unique demands of warehouse operations, where durability, load capacity, and maneuverability drive efficiency. These casters—constructed with thick steel brackets (3-6mm) and wheels of polyurethane or nylon—support 800-5,000kg, easily handling palletized goods, bulk storage containers, or large inventory carts. Polyurethane wheels (85-90 Shore A) are a standout choice, offering low rolling resistance (20% less than rubber) to reduce operator fatigue when pushing loaded carts through narrow aisles. Their treads resist wear from constant contact with concrete floors and forklift traffic, maintaining performance even after 100,000+ cycles. Swivel models feature a precision raceway with hardened steel balls, enabling 360° rotation with minimal effort—critical for navigating around pallet racks, conveyor systems, or loading docks. Optional brakes secure carts during loading/unloading, preventing movement on slightly sloped warehouse floors. Sealed bearings resist dust and debris, ensuring smooth rotation in dusty environments. Whether used in order-picking carts, bulk transport trolleys, or dock transporters, these casters enhance productivity by ensuring reliable, efficient movement of goods.
