Applications

Hospitality housekeeping carts and luggage transport Medical equipment stands and hospital gurneys Library book trucks and archival storage movers Retail display racks and point-of-sale fixtures Light manufacturing assembly line trolleys Office furniture and modular partition systems Food service utility carts in noise-sensitive zones The thermoplastic rubber tread is specifically formulated to resist degradation from common industrial chemicals, oils, and solvents, ensuring reliable performance in diverse working conditions. Unlike hard plastic or metal wheels, this TPR compound absorbs shock and prevents scuffing on vinyl, tile, epoxy, and polished concrete floors. The steel mounting plate measures 3.6 inches in length and 2.5 inches in width, providing ample surface area for secure bolting to wooden or metal substrates. The overall unit height of 5.1 inches allows for sufficient ground clearance while maintaining a low center of gravity for loaded equipment. Each package contains 20 individual casters, facilitating bulk replacement or new equipment outfitting for large fleets of mobile assets. This product represents a cost-effective solution for facilities seeking to upgrade from noisy, floor-damaging casters to a quieter, more efficient mobility system without sacrificing load-bearing capability.
