LD-187 Heavy Duty Industrial PU Rubber Caster Wheel | Wholesale Supplier

The LD-187 Heavy Duty Industrial PU Rubber Caster Wheel is engineered for reliable mobility in demanding industrial, commercial, and institutional environments where equipment needs to move smoothly and safely across factory floors, warehouse aisles, and commercial spaces. The wheel tread is molded from high-quality polyurethane (PU), a synthetic elastomer that combines the shock-absorbing properties of rubber with the durability and load-bearing capacity of hard plastic. PU tread rolls quietly on concrete, tile, and epoxy-coated floors while resisting oil, grease, and most industrial chemicals that would degrade natural rubber. The wheel core is available in reinforced nylon for light-to-medium duty applications and stamped steel for heavy-duty loads up to 300kg per wheel. A precision-machined ball bearing race in the swivel head provides smooth 360-degree rotation with minimal steering effort, while the double-ball race design on larger wheels ensures stability under eccentric loading. The mounting plate is zinc-plated steel with pre-drilled holes for standard bolt patterns, compatible with most trolley frames, equipment bases, and machine stands. Total lock brake options are available on swivel models, simultaneously locking both wheel rotation and swivel head rotation for secure stationary positioning. The comprehensive size range from 75mm to 200mm wheel diameters allows matching caster capacity to application requirements, with larger diameters rolling more easily over floor cracks and thresholds. Whether outfitting warehouse picking trolleys, adding mobility to factory equipment, mounting workbenches and machine stands, equipping medical carts, creating mobile retail displays, or building material handling platforms, the LD-187 industrial caster wheel delivers smooth, quiet, and reliable mobility.
