4 / 5 / 6 Inch Heavy Duty Steel Core Green PU Caster Wheels
These heavy duty caster wheels feature high-quality polyurethane (PU) tread bonded to a rugged steel core, engineered for excellent wear resistance, shock absorption, and long service life. The green cast PU material offers a balance of strength, smooth rolling and floor protection, making them suitable for frequent industrial use. Precision double ball bearings provide stable 360° swivel motion and low rolling resistance to facilitate easy movement under load.
Designed for industrial mobility, these caster wheels are perfect for equipment trolleys, utility carts, game carts, workshop platforms, and other mobile systems that require reliable movement. The swivel and fixed mounting options allow for flexible direction changes and stable straight-line transport, while optional brake models provide secure stopping and positioning as needed.
These green PU caster wheels are ideal for a wide range of industries including warehouses, factories, logistics centers, workshops, and commercial facilities. They work well on machinery carts, service trolleys, storage racks, assembly line carts, display equipment, and other mobile units where medium to heavy loads must be moved repeatedly.
