Applications
Heavy-duty industrial cart transport Warehouse order picking systems Manufacturing assembly line equipment Hospital and healthcare facility gurneys requiring quiet movement Food service distribution racks Audio-visual equipment stands needing stable positioning Library book trucks and archival storage movers Product Performance and Durability The integration of a high-grade polyurethane tread with a solid iron hub creates a balanced solution for facilities that cannot compromise on floor safety or equipment longevity. Unlike softer rubber compounds that may deform under extreme weight, the polyurethane formulation used here maintains its shape under the full 616 lb rating, ensuring consistent rolling efficiency over time. The fixed stem mechanism is specifically designed to prevent the wobbling associated with swivel casters, which is critical when moving tall or top-heavy loads that require unwavering stability. The overall dimensions of 4.5 inches in length, 1.96 inches in width, and 5.71 inches in height allow for seamless integration into existing machinery frames without requiring significant modifications. This product is supplied in packs of two, facilitating easy replacement or paired installation for balanced weight distribution on four-wheeled platforms.
